I just want to say that this video and the tracer bullet videos have been invaluable - excellent tutorials and I wouldn't have been able to create my first animation without them! Thank you so much!
Wow, thank you so much for your nice comment! It really thrills me that these tutorials are both helpful and beneficial. Good luck with your Blender endeavors!
Awesome tutorial!! I had problems getting mine to work, solved by using Ctrl+A to apply rotation to my propeller at frame 0 (in case anyone else had the same issue). Then it worked like a charm.
Awesome video! :D But: KEEP IN MIND THIS METHOD IS ONLY ACCURATE FOR CONSTANT SPEED PROPELLERS! If you for example have the throttle to 0 (y-axis position 0), and immediately set it to 1 in frame 2, then in frame three the propeller will have rotation 2 (throttle 1 * frame 2 = 2). So a rotating speed of "2 rotation per frame" for that frame. However if you have throttle at 0 until frame 100 and set it to 1, you will get it to have rotation 100 in frame 100. "100 rotation per frame" in that exact frame, as it speeds to "catch up". So you cannot control the speed of the propeller using this method, unless you have a constant speed. Earlier this year I had a commercial project where I needed to animate the speed of the propellers on a drone. That is, not just making it spin, but making the speed at which it spins change over time, like throttling up and down. I initially tried your method (didn't find your video before now so giving my advice here now), but I ran into the challenge I mentioned above. The answer was a simple python script for solving the propeller position for each consecutive frame. So essentially, using the Blender python api (bpy), grabbing the local space position of the throttle (which was parented to the drone), and multiplying it with an arbitrary scaling constant, and adding this value to the rotation of the previous frame to get the rotation of the new frame. I ran this script every time I made a change to the animation in order to get the throttling up and down just right. The pseudocode looks like this: frame_0_rotation = 0 for frame in scene: next_frame_rotation = current_frame_rotation + current_frame_throttle_position * scaling_constant using the Blender python api to access and edit any involved variables. Also, in addition to enabling motion blur like in the end of the video, if you want that "bendy" propeller look like there is in one of the examples in the video, you need to enable rolling shutter. I hope someone somewhere will be able to get past a problem thanks to this comment :)
Thank you very much for this very informative comment!! Back when I made this video, i didn't have any understanding about like coding and python, I was actually trying to make a modern version of this tutorial from one that had been made in like 2009 using something like Windows 2000! 🤣 Anyways, once again thank you for this awesome info. I may have use of it for myself in a later project!!
Oh okay. Well, the farther forward that you move the cone empty, the faster the object spins. Now it won't look like it's rotating very fast in Blender, but when you render the animation, you will notice that your object will be spinning very fast. How this helps!
Okay, just go into edit mode and line the object up with the point of origin. Then go back to object mode and the propeller will spin in the correct place. If you need any further assistance, I'd be glad to help!
Great question! What you do is set a keyframe for while the cone empty is further forward (as it should be when the propeller is spinning) then after several frames (I recommend about 100), pull the cone empty back to a zero location. In other words, bring the cone empty to where it was originally to make the propeller stop. Set a keyframe here and the propeller shoud look like it slows down to a stop.
It probably means that at 1:48 you didn't have the propeller selected when you added the driver. The video is somewhat wrong here because it shows the BF 109 selected while I'm adding the driver.
Hi thank u for your help !!!I saw your lessons and i decide that your video tutorials way easier to get than others, i have a request for u , could you make a video about modeling Helicopter Mi-8 or fither f22 in higth poly mode , with detallization , thank u in advance !
Hello! Thank you for watching and leaving a nice comment!! I'm very glad my tutorials are helping you! Unfortunately, it's not likely that I'll be able to upload a tutorial on modeling those objects due to the fact that I honestly wouldn't consider myself a good modeler. Also, college has made me really busy, so my uploading speed has unfortunately slowed way down. 😕 However, there are probably still many RU-vidrs who have made amazing tutorials covering how to model those objects!!! Once again, thank you for your nice comment and for providing me feedback. It's much appreciated!! Let me know if I can be of any help!
when i make a driver keyframe on the plane, and go to the driver window and select my proppelar my driver menu dont show up. and i also dont know how to parrent my plane parts together (cant find any tutorials) my plane has difrent folders for the difrent parts of the plane.
I want to turn my propeller on the Z-axis but I couldn't manage it. It turns on the Y-axis for all the selections of X-Y-Z Locations of throttle. Could you please help me about that?
Keep in mind that it may appear like your propeller is spinning slowly... in reality it could be spinning very fast but the frame rate at which Blender displays the animation as well as the lack of motion blur can make it appear to move slowly. A good way to check this is to enable motion blur and render a quick animation to see how it looks. I don't remember how to reverse the direction of a propeller, but I'm pretty sure you could just create a completely new empty and repeat the process in the tutorial but negate some of the values (e.g., y = 5 -> y = -5).
@@jbblenderbreakdown4668 goddamn you are fast. I will absolutely try that, just one more question: Is there any way to make it start slow and then gradually get faster? Im rendering a cinematic for a quadcopter drone and I need my first person view to show it start up slowly instead of just activating in mere seconds.
@@jbblenderbreakdown4668 Alright so I just tested it and its somewhat fast, but the animation isn't really too fast for what I need. Any idea how I can increase the speed?
@@ArandomHitman Yeah just set keyframes for the position of the cone empty and have it slowly move forward (which controls the throttle/speed of the propeller). The further forward the cone empty is, the faster the propeller spins.
@@jbblenderbreakdown4668 Yep, just found that out. Interestingly enough, that caused one of my textures to glow like the sun, but I guess that's a me issue for now. Thanks anyways.
Great tutorial. When I export as an mp4 I still don’t see much blur on my propeller. It looks good when it’s rendering image by image with eevee, however. Is there a way to make it look better? Thanks
Hmm. I think that if you increase the distance of the cone empty that will increase the speed of the propeller and will make it blur more. However, if that doesn't work then you can try decreasing the distance. Also, try increasing the motion blur setting in the render tab if you haven't already. Hope this helps!!
@@eternalself No problem! The motion blur setting should be under the render tab somewhere, unless Blender has changed in a new update... I've been so busy recently I haven't been able to get on in a very long time.
Just drag the center of the propeller in edit mode to the origin. Then go back to object mode and the point of origin should be in the center of the propeller.
Hmm... Pressing "N" should bring that menu up unless the shortcut was changed in the User Preferences. I don't know why it isn't working for you, but I will let you know if I find any answers. Sorry about that.
@@layrik-7951 Man, I wouldn't know what to do at this point. The "N" key should bring out the properties panel, but if it isn't doing that for you then something isn't right. I don't know what to say here, sorry. I will still let you know if I find the reason for this error. But thanks for the feedback, I do appreciate it.
@@nurazraiaidil7528 The propeller should be a child to the rest of the airplane, that way the whole airplane moves around as one piece but Blender still considers the propeller as a separate object.
Thanks for the clear examples. Everything worked first time! I have one question if I may? To adjust the propeller speed you just slide the empty up and down the Y axis? I can't seem to get it to spin really fast.. Thanks!
I'm glad it worked out! Yeah to adjust the speed of the propeller you slide the empty up and down the Y axis. Keep in mind that moving it even a tiny bit will adjust the speed tremendously. Also it will seem that it isn't spinning any faster, but this is because Blender is displaying the frames to you at a certain frames per second that makes it difficult to determine how fast it's really going. You get the same phenomenon when recording a helicopter's blades. It will seem that they are spinning very slowly or sometimes not even moving at all. Just adjust the empty to a place that seems to make the propeller spin faster and remember to turn on motion blur for realism. I've run into the same problem, and the best thing to do it just keep experimenting with the empty. Hope this helps and if you need anything else, just let me know!!
wait so you just dont explain HOW to do the one thing i need? awesome great turtorial. literally just needed to know how to make a propellor independent to my plane but still move with it. You say i need to do that but you dont say HOW.
I understand. It's been several years since this tutorial was uploaded and Blender has updated since then. I don't remember how to remove a part from a model off the top of my head, but you would need to go into edit mode, select all of the vertices of the propeller, and tell Blender to remove that from the model. Just look up a recent tutorial on RU-vid about how to do that. To make the separate propeller move with the airplane, just make the propeller a child of the airplane (which would then be the parent). If you don't know how to do that, there are numerous tutorials on RU-vid about how to do that. If you have any further questions, let me know!
Hello! In my animated movie, "The Altercation" ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Q5wV_QiXuRs.html I used an HDR Image for the world setting. This Image was quite realistic, with great detail in both ground terrain and clouds. That way I wouldn't have to make the clouds, which would've slowed down my render incredibly.
@@LucasTrys You're welcome! This is the image I used: www.hdri-hub.com/hdrishop/backplates/hdri/item/868-hdri-dome-loc00184-22-above-clouds It was a free download when I downloaded it, but I am not sure if it still is. Let me know if you need any further help!
@@LucasTrys Yeah, something like that. I went to the world settings in Blender and selected "New". Then next to the color option, I selected the tiny dot and clicked "environment." Then I clicked open and then my downloaded HDR Image, and it worked amazingly!
that was really good and helpful sir, and can i ask you a question?, im new to blender(still two days), i want to ask like.. how did you make the uhh aircraft and its propeller separate and when you move the object the propeller still on the aircraft and not going anywhere ?, i know you've been told it in the video that the object was parent or already linked, but how?, sorry for my bad grammar
it will be really helpful sir, cause when i download model like tanks, it all separate, but when i tried to rotate the canon, its going somehow uhh(its rotating but with a big radius rotate, also the canon leave the tanks behind) i just want to know how to make it rotate, but in the place that it should be, im sorry for asking this
and also hahaha, i know im still need to learn the basics, i use element 3d before, but it was totally hard to animate in element 3D(coz u cant just like do lke blender can do), talk about element, i should use c4d then, but i wasn't, some say it more harder than blender, so yeah
and just like obj file, the object.., when i clicked it, i clicked the whole object(not the side that i want to click), but when i go to edit mode, i can touch everything
Hey, I will try to help as much as I can, however most of the knowledge that I gained about Blender came from just watching tutorials mainly from Tutor4u's channel: ru-vid.com The idea is to keep learning and experimenting. Over time, you will learn how Blender functions and little tricks to make your work faster. I found that downloading models can help you understand how to use edit mode, along with basic animation. Because the Blender community is so large, there is basically no question about Blender that is unanswered both here on RU-vid and on Blender's website. My highest recommendation is to just follow beginner tutorials like I did, and this will help you to know and understand Blender. By the way, to link an object to a parent, just go to the outliner and drag and drop one object onto another while holding shift. And also, your grammar is just fine 👍 Hopefully this helped you, and if you need anything else, just let me know!🙂
@@jbblenderbreakdown4668 thank you very much sir for your advice, i will ask again about something that i don't know later, now i know a bit to separate object without leave it behind(like when u move the main object, the object that have been separated will follow too), yea you're right, need to go to edit mode(and mess with things there), take sometimes too to do selection to the dot and right click then seperate
Excellent question! To do this, at 4:55 move the cone empty in the other direction (to the right). This will make the propeller spin the opposite way. This worked for me, and if you need any further help, just let me know!
@@revcus7437 That's definitely a possibility. But I'm pretty sure the settings used in this video weren't changed dramatically and so should produce a similar result. I'm not sure though.
I did have Icecream Screen Recorder on my laptop while making this video, but I did not use it to record this video or any others on my channel. I'm sure this software has some potential, but as of now the free version is way too limited.
