VroidStudio Unity How to attach Tails new edition 

Thank you for sharing! 😊

How you do all of these? I'm lost in Unity :(

my errors are all VRM 10/universal render pipeline and runtime mesh utility NVM i fixed it

@@sleepymonstersstudio1227 I am so glad you find it useful! I also use this method for a lot more than tails ^^b

That's awesome! Glad the video helped 😊

Awwn, thats so sweet of you! I am working on a comeback! (I had just a lot of unexpected stuff happening q_q) If everything goes well, I could be back as early as next month. :)

@@LadyAska Yay! Hope that everything goes well!

Thank you for the head's up! I can make a little video about that specifically, as this problem wasn't present, when I initially made the video.

@@LadyAska In that case, I would also make sure to specify versions that we know work very bluntly lol, it can definitely help with that confusion.

@@ZetaMAGES Will keep that in mind, thank you! :)

I am so glad it was helpful! ☺️

Awn, sorry that this didn't come through the right way. (I could've sworn I had it in the script q_q')

@@LadyAska Nah, it's ok. Just make a quick add-on! "Sorry, folks! I forgot _another cool feature_ of the updated Bone Weight Transfer Tool! Blahblahblah..." Then show them how to do it. :D

Thank you for the heads up! I didn't use this version yet on a multiple-avatar project, so I had no clue! :)

How do I fix the taffy pull glitch?

@@Aqua_Autie_1 I remade the tail using a new hair mesh in VRoid Studio 1x.

@@panelvixen sorry if I ask a lot of questions heh, but what exactly is vroid studio 1x?

@@Aqua_Autie_1 Shorthand for VRoid Studio version 1 through 2. In programs there tends to be a lot of numbers and periods used so I condense it down using the letter X. Another example was Windows 9x was shorthand for all versions for Windows 95 through Millennium.

I know, I felt the same in the beginning. It gets better the more time you spend with each one and just take it slow. After you get the hang of it a little bit, it gets so much easier and the insecurity goes away. You got this! :)

I am so glad to hear that! :D

Absolutely! Finally no tail attaching in Unity anymore! (and the tails look cute too :3 )

I never heard about something like this. How much hair/bones are in that ribbon of yours? Sometimes when its a lot, it can take a lot of time and if you don't get it to work this way (transferring all at once), try to go by a few at a time or even just one at a time and repeat the process until all hair of your item is successfully transferred. :)

​@@LadyAska It worked perfectly! I've tried reducing some of the bones, it seems to work much better with a 2021 version, just like the video (I had a 2022 one), and checking that the two options are unchecked when exporting the vrm initially in VroidStudio really makes a difference. I'm so happy it worked, i've been waiting this for months, thank you so much!!

Hello! I do! Life got a bit busy atm and I am learning Blender (which sadly takes a lot more time then I thought), so I can create more cool content for you guys after. Hopefully from a new place soon as well (I am likely to move in the next 6month, if everything works out) so that is ahead as well and will mean more regular content again, since my recording time will not be interrupted by other factors anymore. 🙂👍

You are very welcome! I am glad you are enjoying them! 😊

I never had this problem. If you want to see if we could solve it, feel free to contact me on Discord. (@ladyaska) I assume it's something that happened maybe during export, but would have to check that on the model itself.

i have the same problem

So I learned what it was since I'm working on a model rn and had to mess with it again, but not how to fix it. So I was using the hairs attached to the head, because despite me doing everything correctly, exporting with the same version of vroid, having the same versions of everything etc, for some reason when I import my vroid model into unity, I do not have a dropdown for hair (like in 2:24), I can only see the hair on my model when I go to the neck dropdown. I have no idea why and I've scoured a ton of different tutorials to try to find what I'm doing wrong, but everyone just seems to magically have this hair dropdown while I don't. Even if I don't duplicate and convert to vrchat and just upload the model as is, I see "hair" but it's not a dropdown, it just lets me click and see all of the hair. I do use unity 2019.431 but that's because I have an issue with vrchat SDK not uploading, so I have to use it, but I don't think a different unity version would cause me to be missing out on an entire dropdown.@@LadyAska (Edit: quickly tested in the other version of unity and still don't have the hair dropdown.)

If they put the limit, then that's likely what you are stuck with. For tentacle hair though, I would still do it with hair actually, since you can put a bunch and you don't have to reattach anything after, since it's already on the head 😊 (they have bones too, btw, that you can put yourself...while the new tails come pre-boned ...so no way of customizing anything 😅)

What other files are you trying to load in?

Hello! That is easy to solve! You just aren't in prefab mode yet! Just find your Avatars name on the left hirarchy and there is a little arrow on the right to the name...if you press on that, you switch to prefeb mode. Then drag your bones again, like you tried it before. this time it should work ^-^b

@@LadyAska OMG thank you you're a savior, I will try to use the same boneweight transfer to put a broche made out of hair on his chest anchor I think it could work right? :d Thank you for giving us guides for these super helpful assets

@@justafish9618 It will absolutely work! You just have to put at least one bone into the asset and then move it under the section it should be linked to. (If its on the "Upper chest" for example, you would put it there :) )

@@LadyAska Oh god I don't think I put any bone there since I didn't want it to move...

@@LadyAska I'll change the source form head to upper chest and se if it will at least stop it from moving all over the place following the model's head movements, it might do nothing but it's worth a try :d Update: it worked!

Ok, i got it sorted. all good

Yeah, I heard it’s going pretty bad atm. I don’t know what Unity did, as nothing else changed. I also get a lot more errors as of late. I am using atm the old Unity version 2019.4.31f1 with univrm 0.92.0 and even with a few errors it usually works

@@LadyAska i got things to work, but the transfer never told me if it finished and the next step wasn't needed, since i tested and the tail works fine. at least i have a way that works though.

Hello! This usually means that you probably forgot one bone during the moving process (from manually moving it from head to hip) or that (if your tail has multiple parts), the bone weight transfer wasn't applied to all strands. If you can't figure bit out, feel free to message me on Discord and I can give a look, if you like :)

@@LadyAska The tail is made of 1 Hair Strand, I got everything, I transferred it, but the tip of the tail is still attached to the head and still moves with head.

warudo looks amazing so far. I am planning a whole series about it, once I moved and settled into the new place 🙂

I am glad it helped! :)

For a Vroid model or a Blender model?

@@LadyAska for Vroid Model after importing it to blender

Ok, thank you for letting me know. I was trying to do it in Blender, but it never came out quite right 😅

@@LadyAskaWill you try to replicate the texture of the tail 100% it video ? minute 02:05

@@LadyAska

Feel free to message me on Discord for help. I offer to attach tails for free, if you really can’t get it to work on your own. (I am ladyaska over there)

Hello! You don't at all. Thank you for reaching out :) Did you install the univrm plugin first? (make sure to use both versions mentioned in the video/description of the video, to rule this out as the problem) I am sure it will work after that. If, for some reason, you can't get it to work, don't hesitate to reach out to me via Discord (ladyaska)...so far we got it to work for everyone :) )

Feel free to message me on Discord, we are getting a ton of weird problems lately and I haven't heard this one yet. I am ladyaska over there. Just shoot me a message with a screenshot :)

All of this is only relevant, if you created your tail in Vroid, with hair (size doesn't matter here) :) Without the bone weight transfer and the manual moving of the bones, your tail would just float around you, whenever your avatar moves their head. But usually you want the tail to be firmly attached to your hip/back. All I used in this video, is the mentioned version of Unity and 2 plugins, that you have to download separately. The univrm plugin, to import your avatar into Unity in the first place, and the bone weight transfer plugin, to transfer weight information of the bones from head to hip. If you are using anything else, you would have to explain to me a bit more detailed, what you are trying to do and which tools you used, as I can only refer to this video and won't know what other things you tried and why my solution here, may not have worked for you, for example :)

@@LadyAskathanks I did watch your older tao video and it works!! (I save it) just gotta adjust my laptop storage so once I got Unity and Unity editor ready..I shall install the vrm and those other plug ins right? (And the bones or hair bounce gave to my bunny tail is low or zero to make it near the hip or just small physics) just gotta stick it onto the butt part : D , thanks I shall try once weekends happen for me

Make sure that you have the right versions of Unity and the univrm plugin installed. If the versions listed in the description don’t work for you, then I recommend to use Unity 2019.4.31f1 with univrm 0.92.0 (this is one of the most stable builds I know of

Oh, I think I understand! So for it to appear as a vroid_customitem, your item or tail has to have at least one bone. Otherwise it can't appear. So you would go back into Vroid and add at least 1 bone to the thing you worked on. (if its a tail, add more, if it's a chain, add more, to help with a nice movement later) The thing with bones is, that these will have to be set up beforehand in Vroid and you would need to test the "flowiness" beforehand already, to be sure, it's the way you want it to be. (even though in Vroid, it may clip like crazy) Once you are happy with that, you go into Unity and do the whole bone weight transfer and moving the Vroid_customitem. (which represents the bones, you added before) I hope that helps and didn't confuse further :)

@@LadyAska It seems to depend on the "age" of the model too. My bones were named J_sec_Hair1/2/3_(Hair ID 06 in my case) for the bones IE my eighth bone would be J_sec_Hair8_06 and First would be J_sec_Hair1_06. I Started my model in Vroid 1.22.0

@@LadyAska im having the same problem here, and anything seems to work.

I really hope it helped :)

Hello! Yes, its a common problem currently, but we found the solution! First, make sure it`s 2021.2.17f1 (the video may state different, but I really couldn`t forsee this one) Then univrm plugin version 0.110.0 for VRM0!! (the last part is the important part, because there are 2 versions of this plugin now. If you use the vrm0 version, make sure you also exported your avatar as vrm0!! If you follow all of that, it should work exactly as shown here in the video :)

Maybe you got the old version? Then it is under Tools :) If not, please verify, if you really got both Unity and Univrm versions correct, as mentioned in the description

Did you also manually move the bones after? This is the most crucial part, as explained in the video. If you need more help, feel free to reach out to me on Discord (ladyaska) and I am sure we'll get it to work :) I also always tell you guys the versions I used, so you should be able to recreate the exact environment. (sadly due to the very frequent updates to Unity and univrm, the other plugins can hardly catch up...thats why this is so important)

Yes! Because the bone weight transfer transfers only the information of the weights, not the actual bone. So in your case, no bone, which means you can’t do the second step of actually attaching the bones to the hip or back, or wherever else you want it to be. The only workaround that I found for this, is to put a single bone into the object in Vroid and make sure that it’s as stiff as possible (so no wiggling effects)…you can check that in the photobooth under animation. If you bow does wiggle around, it’s not stiff enough. Then in Unity you apply the bone weight transfer and then move this one bone manually in the hierarchy to the hip.

I could look into it. I am not sure if it will be 100% possible with Vroid, as the MToon shader has its limitations, but since we have see through glasses, maybe there is something to be done. Thank you for the sugggestions! :)

a veil could be made semi-transparent with a dithered texture. Someone made a black fine mesh top on Booth that's literally every other pixel is black/alpha alternating. Looks great.

When in the process are you getting this error?

@@LadyAska In BoneweightTransfer > Seperate Mseh Mode

@@KDemon114 This could have so many reasons now: Check if you used the right versions of everything. Are your meshes really separate or did you accidentally combine them during export? Check if you exported with vrm0 and not either vrm1 and if the univrm plugin you are using is for vrm0. I have to assume that you did the rest correctly, as shown in the video.

@@LadyAska Thank you so much I can fixed it. Thank you ❤

Hello! Sorry for the late reply (timezones and all 😅) I would recommend learning how to use Blender. I will start with that as well, beginning next week, because Vroid is just so very limiting and the hair method is not always a good workaround. I am sure you got this! :)

To be honest I tried a few necklaces and scarfs and the likes and it usually doesn't look good. The reason is, that you need to put at least one bone into the item you are attaching this way...which means your necklace will wiggle around like crazy. Maybe you just have to find the right setup though. An idea would be to not put any bones around the back of the neck directly, but just around the front area. (but for that you would need the necklace to really be made out of pieces of hair and not an Image of said necklace) If you can find a free 3D asset of said necklace, I would probably recommend that, instead of doing it with hair. 😅

What happened between the last success launch/use of Vroid and the one you are having problem with? Did you install a lot of new software, some new games maybe? My first guess would be, that you simply ran out of space on your SSD or Harddrive and/or your RAM is used elsewhere. Give a look at how much free space you still have, open up your task manager while trying to launch VROID and see if its taking up a lot of processing power, as well as space on your drive/drives and maybe clean up/uninstall some software that you don't need anymore. You can also run programs like CCleaner to get more free space. That's just my first guess, without any further context :)

Make sure you are looking at it from the prefab perspective. (on your left hierarchy, when you drag your model there for the first time, there is this little arrow besides their name...not the one to open up the root and all, but on the other side. That opens up the prefab view) It can be, that your bone has a different name, usually something with hair1_01(the numbers change obviously). Mine pop up sometimes somewhere in between and there is really no system to it :/ If you need more specific help, feel free to message me over Discord directly and I can check some screenshots of your problem, until we (hopefully) find a solution :) (I am ladyaska on Discord)

i send you a message on discord

Yeah something is up atm. I had another user report the same thing yesterday. If you don't mind, feel free to send me your model over Discord and I'll try to attach whatever you need. It's also for testing purposes, if anything during a Vroid update caused this or what's exactly happening here. This is a recent problem and not normal! My username on Discord is: ladyaska

Thank you so much ! I added you on discord ^^

You can do that in Vroid itself. I think in an older video about 5 useful tips, I displayed how to do that. (you would just edit the texture, to include your logo on your shirt, or as a tattoo on your arm etc ) :)

@@LadyAska Would you know how to do it in unity because I’m trying to attach a image to a accessory that’s already attached to my model,

@@jayosonic yes, in this case, take the texture from the accessory (it's in the texture folder, after you import your model) and right click onn it. Select "show in explorer" and open up the file shown in an editing software of your choice (Photoshop, Gimp or whichever you are using to edit textures usually) Add your logo and then save everything. This should automatically update the texture in Unity as well. Now if your accessory is a third party item, it can be that you have to work with a texture atlas (all textures of the item cramped in one place). This would make in nearly impossible to add something to it. In any case I would save the original texture somehere first and then edit a copy first to test it out. Fir this you would have to create a new material in Unity (don't forget to change the shader to MToon if you are exporting as.vrm) and attach your copy material to it. (importing your own texture for anything, is as easy as dragging and dropping the texture file into the texture folder...from then on, you can use it on a new material. Then you would drag that new material to your accessory to use it (and check if the logo is in the right place), if it isn't, change back to the original material :)

If you say "changing clothes", do you mean creating new cloths for Vroid models or changing the clothes, once the model was already exported? I heard there is something like a "wardrobe" app on booth, would have to find the link for it...can't really say if its "easier" though...Vroid does it all in one spot and setting the cothes up to be traded later in Unity isn't too hard as well, once you got the hang of it. I don't know if we have something yet, that makes cloth switche easier...maybe give VNyan a look...I didn't have time to test it yet properly, but I heard you can do some really cool things with it. :)

OK, thank you :-)

No wait, I already figured it out!!!! Looking for information I found that there are some bones called J_Sec_Hair with numbering, just by taking the one corresponding to the tails and moving it to the hip, I managed to get everything well anchored. I cried with happiness.

@@RenataRengoku5941 Good job! My hair is just named customitem, because I used a premade tail. The J_hair etc. ist much more common. :)

@@LadyAska ooooohhhh I seee, I was losing my mind xD

There is an older version, but the only difference is, that the interface looks different and the tool itself is found under "Tools". But if it "isn't working" the reason usually a different one. Before giving up on it completely, double check the following: 1.Are the Unity/univrm versions the exact one, mentioned in the description of this video? (if not, I highly recommend you download the correct versions and try again...the difference this makes is incredible) 2. Did you also follow through with the second step, moving the bones manually from head to hip (or your preferred destination)? The bones in my video are called "customitem", but yours could be called "hair01_01" for example. This step is the vital step to really attach whatever you want to attach. If you get an error instead, I highly recommend to contact me on Discord (ladyaska), so we take a look at it. But make sure, that you tried the correct versions first. In very, very rare occasions, the problem has to do with the settings and directions of the bones from Vroid, which then has to be checked and fixed.

@@LadyAska okay Ty so much I'll try few more times

Welp I figured it out, I had the "VRM 1.0 Import/Export" instead of the "VRM 0.x Import/Export"

You can try it, but if you get a problem with this setup, I always recommend our tested combination of Unity version and univrm version. :) Just give it a go and feel free to report back for others!

Which part are you struggling with specifically? :)

@@LadyAska it doesnt show the same bone weight transfer as yours, mine didnt have the + and - buttons

Hello! I hope it is ok to ask to contact me on Discord (ladaska). This I would have to see myself, to verify if everything else was done correctly. :)

Same here

It's so weird, I had like 3 people in the last 2 days reach out to me, because they can't find the bone weight transfer plugin or their model isn't loading. Which Unity and Univrm version are you using? The one I recommend in the video/description? (In case you still have trouble, feel free to reach out to me on Discord. I am ladyaska there :)...I can help a bit better over there, if the version stuff doesn't do it for you)

@@LadyAska I'm using VRM1.0 v0.113.0 and Unity 2021.3.21f1
