SOLVED: There isn't a SOP input in the new particlesGPU, so you have to convert the noise SOP to a CHOP then to a TOP. Instructions on how to do that are here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-5qo3J5vX0eM.html at 20:00.
Thanks for sharing this - great work! My fps was fine at 60 - 1080ti and i9-7900X - and the latest TouchDesigner build - 2020-23680. Non commercial so only initially 1280x720, but pushed to 1280x1280 and stayed at 60 still.
This is a great tutorial. Thanks! I haven't checked down in the comments for an answer to your question about frame rate degradation. But I tried implementing this on a MacBook Pro and was getting circa 8 fps! I'd be strongly tempted to say that the particlesGPU container is the culprit; there's a lot going on in there. Certainly, to my mind, a lot that isn't necessary for *this* particular patch. I tried something similar to this with a straight particles object and got it running at 30 fps. Don't know if I'm missing anything important feature-wise, but I'll take the fps and figure out how to add anything I think need myself. Thanks again. You're doing a fine service here!
For anyone struggling to get a similar look with the new software and ParticlesGPU updates, here's what I changed : * Envelope node -> change "envelope width" to 10 * Add math node between filter and null and apply these values -> From range [0, 1] to range [60, 0]. Basically we invert the drag value and make it more intense, you can tweak the 60 value in the math node to get more or less effect
Thanks this was great. Would you ever consider doing a more real time tutorial where you discuss why you add each node on the fly? So we can know your thought process.
While I think it's nice to be able to follow a project tutorial through and have a nice looking file out the other side, it can be better to try understand the nodes before you try follow and watch with understanding.
Thanks man, great tutorial. About the fps, I noticed that inside the particleGPU all viewers are by default activated. I seem to remember that disactivating all helped quite a bit. Just a thought.
Hey there. The issue with the frame rate seems to be the setting of parameters. Try setting them not by referencing a CHOP, but by writing to them from a chopexec1 from the CHOP that is supposed to control it, so for instance op('particlesGpu').par.Drag = val and so on.
Man this is soooo awesome! I made my first ever project with this! Thank you Sir! I look forward to supporting you on Patreon and any other way possible. :) I have a noob question: How could one automate colour changes over time? So in other words, the colours change as time goes on. :)
Can you please explain this a bit more? I am familiar with optical flow and trying to expirement with this.. do you connect optical flow to the TOP input of particlesGPU or the SOP input. Do you do any other tricks to get it working? thanks for your help!
thanks again and again for your time and energy putting these together! Now if I can figure out how to make particle clouds turn into different forms from reacting to live audio - shazam!! that said, I'm a newb so, probably not! lol
for live audio you can just use an "audio device in" CHOP (select the microphone or audio interface you want to use) and plug it in where he is using audio file in CHOP
Great Tutorial! My guess on the FPS drop is the lumablur top, if you have the filter width set pretty high. When I tried this for a project, my FPS instantly dropped from 60 to under 40 FPS, so I ended up using a blur top, and composited the ramp-masked blur version on top of the original to create the same effect without the lumablur..it's the long way, but didn't have the same FPS drop.
Might have figured out the fps issue. Atomic counters aren't supported on Mac in TD. I noticed that the reference in the glsl top was 0 so I removed them still works and it gave me 60 fps.
how has no one else ran into the problem of not being able to connect the Noise SOP to the particleGPU TOP??? It literally does not allow for a connection. Is this because touch designer was updated since this came out? I cant even get past the beginning of the tutorial because of this. Sigh
Yikes! I've learned a lot from your style of explaining things. although I am stuck here with exporting, I have followed ur another tutorial on exporting. But, whenever I hit record button, the playback stutters or lags in between, and at a specific point of the audio part. Help me out, I have an amazing vocal mix to go with these visuals.
Thank you so much! This one is not complicated in constructing and very nice in sight. Can you give a hint how you can make the particles follow some path? Of a noise CHOP for example. If you make it a SOP maybe.
I was wondering the same thing. Im only just getting started with this software and was thinking about possibly adding a displacement map, that would cause the particles to morphe into a more recognizable shape. Perhaps a face or anything figurative.
Another brilliant and professional tutorial thank you so much! I learnt something new with each one. Is there any reason to use the particle SOP instead of the particleGPU tool?
Thank you! Well technically using the particlesGPU should be many times faster to process. Any process on the GPU is a lot faster, it's why GLSL is so powerful for example. Idk why it's not properly working here. But afaik they're working on a new particle TOP exactly for the reason listed above. Does that answer your question?
I loaded an old version of teh software it was pretty easy to find 2019.20140 27 Nov, 2019. the only thing i have an issue with is I get to much spin on the particle groups sometimes.
Thank you soooooo much - THIS IS AMAZING!!! I have a much better understanding of the system after pause/play, pause/playing through this tut. Took me about 2 hours to get through this 16 min vid. btw - are you Taron of VervePainter?
4:04 Noise and particlesGPU are not connecting to each other. It was said that it was due to the difference between the old and new version. A solution map video would be great.
Anyone know why my background won't turn black like his when I connect the level to the ramp + lookup at 3:05. Also what were the three competes he kept in the beginning of the video?
thank you for the great tutorial. when I try to export the video, it's black with no sound. do you have a tutorial for exporting or maybe you've shown it in one your videos?
Huge fan of your tutorials, I have worked through most of the beginner course at this point. Thanks so much for all the content you share! Unfortunately, this is the first tutorial I've struggled with, I can't get my particles to behave at all like yours do. The drag parameter doesn't seem to affect the particles at all.
I was looking in comments, is this been resolved by now, and how to proceed without SOP input in ParticlesGPU, and found out your comment here asking the same. This is an obstacle for me at the moment, don't have workaround :( shame
Awesome tut! I'm trying to get the ParticleGPU working on my M1MAX Macbook. But I get this error: 'Geometry Shaders not supported on this GPU or OS.' I guess not supported because of no OPENGL? Is there a work around? PS: the particleGPU also doesn't have a SOP input, is it because of the same thing?
Hi! I'm following the tutorial but I have to problems, in the particlesGpu can't find the presets menu /: and also, how do you make your background show the work in progress? thank you !
Thank you for the tutorial! BTW does anyone know how to use imported fbx instead of sphere? Want to put some visuals but fbx mesh doesn't work independently without info in/out
Okay I've gone from the noise operator to a 'sopto' then a 'chopto' but the only values that work are the 'rgb' values. Im using version 32050 which is a further update from the link below so that doesn't work either.
For some reason the drag is not slowing down the particles for me, even when I don't use the audio and just use a constant value. Anyone a clue what is going on here? (I am using a newer TD version than in the video here)
heyo! so on touchdesigner version 2022.31030 particles GPU node doesn't have "presets" tab as well as "turbulence speed" options, nor SOP input(someone already mentioned that). i copied the particles gpu node from your file and it imported with those options so everything is good now, but i wonder why that's happening and what's the workflow for that step for future references if i have to use that node again. cheers!
Fantastic Tutorial! I'm having trouble getting the Luma blur to act in the same way it does in your setup. As soon as I drop in the luma blur and connect the ramp, it applies a transparent gradient to the background. It's a bit hard to describe, but there doesn't seem to be the same tilt shift effect at all. Any idea what's causing the luma blur to act so differently? I've watched that part over and over again but can't find a difference in the params either.
Such a great video - I have learnt so much from you and this is what I have particularly wanted it for - visualizing audio ........But......... with a more recent version dragging the audio nulls over the turbulence and other ParticleGPU parameters makes the visuals from ParticleGPU onwards just disappear and I get not nothing. I have tried using op('null3')['chan1'] etc and it changes the value just nothing happens on-screen. As a TouchDesigner newbie I would really appreciate it if someone has a solution. Thanks very much.
mines running at 60 fps but it looks like its running at 30 lol maybe my song is too fast. ill have to try to tweak some stuff. thanks for the tutorial
there s a matter new particle gpu is completly different another perform totally different for example there are not presets and cant select sent you need to choice between others option

This is awesome! How do I preview the render on the background?
