Animation, Rigid Body and Cloth Simulations in Blender 2.91.0

[@dklchau]

One of the very best examples of instancing rigid body animation on KZbin! Thank you!

[@Blendini]

Wow, thanks! Glad it was helpful!

[@Jaconiel]

Excellent solution - fixes the conveyor belt challenge!

[@MR.ADIVINANZA]

you are underrated, you make very good videos!

[@ryanmlukas]

Brilliant tutorial. Great explanation with multiple ways to complete the task.

[@RohitVerma-ij9do]

Finally i found what i was looking for thankyou. Can you make a video on a machine conveyor 3d made in solidwork and import 3d model to blender and then make that conveyor moving animation on blender ?

[@jeffosborne440]

This was an amazing Tutorial. Fantastic job! Everything was very well explained and not rushed thru. Saving this in my reference folder. Really looking forward to seeing more like this. Thanks Very much.

[@Blendini]

Awesome, thank you!

Underrated

[@turke785]

Thank you for this content. Education has benefited me a lot

[@rhomis]

I have done a few different conveyor tutorials and all of them are pretty much the same. This one is the best. However, it seems very unstable if you make the slightest adjustments. Too much bounce not enough bounce. Box disappears. Box lands above the belt. If you don't want to drop the box, and just have it on the belt, it drops through the belt. Clearing Scene Properties cache doesn't seem to do much. Reloading a saved version of the project seems to have a positive effect in many cases. It seems like this shouldn't be this difficult. Oh, and I want to drop without bounce.

[@Blendini]

Some of the rigid body issues you mentioned above are addressed in this tutorial -> kzbin.info/www/bejne/pmObg3mvqaZ0f9E After checking those issues, to make the object land and stick (no bounce) increase the friction for both surfaces. Much of rigid body activity depends on picking the right collision shape for your objects-- the linked tutorial talks about this in more detail, but picking the right shape involves a bit of trial and error.

This is so cool, Thank you Sir.

[@ronioclarenzo6137]

Fantastic tutorial! Very thorough and very informative! Keep up the great work!

[@Blendini]

Thanks!

[@CheerleaderTW5566]

great help I almost found this over a month

[@CanadianBatman1]

I followed everything exactly as you did. My box falls through my conveyor belt. Wondering if there’s a work around, or something I’m doing wrong. Your instructions were very concise, so I’m at a loss as to what I did wrong.

[@Blendini]

I'm not sure what might be problematic but if you want, you can send me the file via blendiniyt(AT)gmail.com. I'll take a look at it and hopefully find a fix.

[@CanadianBatman1]

Your offer is extremely generous. I decided to start your tutorial over, and now it works as it should.

[@robertesaldisamuel2930]

I have the same problem here. what should I do??

[@antonzhavner1750]

Amazing tutorial, thanks

[@jeffosborne440]

are there guidelines you have to follow when you place you cube initially? I did get it work when I dropped it in the middle of the belt but when I tried to drop it from the starting end of the belt, the cube just flew up and of the screen...

[@Blendini]

No guidelines for cube placement; the issue you're experiencing is likely related to the curve modifier. Around 3:00 I flip the conveyor belt around the y axis so the top of the belt moves in the same direction as the object origin when it's moved along the Y axis. This transformation was used to work with the negative Y (-Y) deformation axis, which may be responsible for unexpected animations. Try switching the curve modifier deformation axis to positive Y (Y). Then rotate the cube/conveyor belt along the Y axis until it is properly oriented along the curve object (usually 90 degrees). The movement of the top of the belt must still align with the object origin in order to get proper collision animations, so make sure they still move in the same direction after these changes.

[@jeffosborne440]

@@Blendini Very good :-). Funny...I was up last night till 2am and actually for some reason, thought of trying this and then yes, it worked fine. You must have been sending me telepathy for me to try that lol. Thanks for the reply and explaining. I really appreciate it. I hope you'll be doing more videos. I shared this one of yours on a FaceBook Blender Group Page last night so hopefully you'll get some new subscribes. Have a good weekend.

[@Blendini]

I'm glad that fix worked for you, and good on you for figuring it out. Thanks for sharing the video. If there's a tutorial you'd like to see, you can always mention it in the comments. Thanks again!

[@jeffosborne440]

@@Blendini I really appreciate your replies, thank you. A tutorial I'd love is one doing just shading and texturing. No modeling...just taking a plane and go thru different types of effects and what Nodes to use....the process breakdown. I just learned a bit of UV unwrapping and applying a texture from a graphic...It was really cool. Derek Elliots tutorials have been really good for me to learn....and now yours too. Anyway...I'm rambling lol. Enjoy your Sunday.

[@Dibyo01]

Thanks it helped very easily put

[@rhomis]

Blender 3.3.0 the cube multiplies in the X direction, when I choose the Y factor.

[@Blendini]

If you're talking about the array, check for unapplied transformations. If you've rotated your cube on the 90 degrees around the Z axis, a Factor X offset on the array, will appear as a Y-offset. Applying transformations will fix this. Otherwise, check out this tutorial which clarifies common issues with curves, arrays and rigid bodies: kzbin.info/www/bejne/pmObg3mvqaZ0f9E

[@rhomis]

@@Blendini - I rotated it. Thanks It seems to work now, but I have come across other weird things.

[@rhomis]

@@Blendini I got things to work. I had to use "keys" to turn off forces and such. A little fakery too. Here's the final project: kzbin.info/www/bejne/hZasdaKOrrKtm6M

[@AnouarBrissel]

Nice and clear!! Is there a way to continue spawning (and make em disappear at the end of the line to avoid blender calculating em?) objects to feed the convoyor? like during 2min or 3000 frames? many thanks

[@Blendini]

sorry, just now seeing this! still need help?

[@famous.football.players7615]

Best❤

[@okangullu]

nice informations

[@Resok96]

Hey first of all very nice tutorial ! Unfortunately it doesnt quite work for me with the belt, because after all rigid body settings you did on both objects the cube falls through the top of the belt and lands in the middle, and moves there. Its the same height the blocks are on before using the curve modifier. It seemed only to work after i set the Cubes shape to "mesh" and collision margin to 1m in the rigid body settings, which cant be the right solution I think.

[@Blendini]

Hey, i'm glad you were able to get this to work. The mesh shape does matter; I was able to recreate your issue but I've had some trouble getting consistent results. I'm going to look into this more and may produce another tutorial that works for the newer versions of blender. Thanks for the feedback!

[@FunMakesMe]

I have the same problem and i swear it's driving me crazy... Tried a lot of other tutorials and other solutions are just to time consuming so i need this to work haha

[@BlueBerryFTW]

whoa so cool! i wanted to learn how to make tank treads and i can use this guide to achieve that! not even what i was looking for here but glad that i learned so much from this, def subscribing!

This is so nice video.

thanks alot .its amazing

[@Blendini]

Most welcome 😊

[@Introx3D]

Nice simulation

[@Blendini]

Thanks ✌️

[@minechannel6096]

hi, my active cube keeps moving on Y axis, never falls down from the conveyor belt. any idea to fix this? thank you for your help!!

[@Blendini]

hi! Check under the rigid body settings for the conveyor belt, and try changing the source to either Final or Base. Final is what should work, because it allows the simulation to take the object's modifiers into account-- but to fix this problem, using Base worked. I'm not sure why. I hope this helps!

[@tcheadriano]

Awesome!!

How to make 90 degree conveyor belt

[@Blendini]

This technique works for any shape that is a curve. If you want to rotate the conveyor belt 90 degrees, select the curve and belt mesh and rotate both of them. Then apply the rotations. Then with the belt mesh selected, tab into edit mode and rotate the initial block to the proper orientation.

[@p.c.windhamparanormalroman4339]

In 2.93 it only gives you 4 vertices. One at each cardinal direction. HAH!!! GOT IT, Had to subdivide. hehehe.

[@ProHolmes]

I'm trying to simulate a box falling into a fabric bag. Bag is cloth and box is rigid body. The bag interacts with the box and deforms, but then the box just fall down through the bag.

[@Blendini]

I've not spent much time with this but there are a couple of things to try: 1) Instead of setting the box to rigid body, try cloth or soft body. If you use soft body, uncheck Goal, and under edges increase pull and push to .99 to prevent the object from changing shape. 2) Ensure that your cloth bag has collision enabled, and try increasing the quality steps of the cloth simulation.

[@ProHolmes]

@@Blendini wow this is a really fast reply! With softbody my cube stayed inside a bit linger stretching the bag but finally went throug it. With cloth it works. I just need to study cloth settings more to make my cube harder.

[@Blendini]

@@ProHolmes Happy to help! I'm glad you were able to figure something out. I'm not 100% sure what you mean by "make my cube harder" but playing around with Stiffness values might give you the effect you're looking for.

[@aleks.l394]

Hey, can somebody help, because cube goes through th cloth. thanks

[@Blendini]

There are several settings that might be causing this-- Is Object Collisions checked on the cloth's Cloth Simulation Properties tab? Starting at 13:10, it shows an animated cloth and a box passing through which shows the other necessary setting: Collision must be enabled on any objects expected to collide with the cloth. I hope that helps!

[@aleks.l394]

@@Blendini omg I didn't expected you to reply. Thanks a lot, I will focus on everything you said and again thank you

[@aleks.l394]

@@Blendini The actual problem was is that collision needs to be after rigid body on the cube

[@Blendini]

Thank you for the feedback, I edited the description to include it!

[@esCodepl]

haha nothing simple :) my pc just burned out trying to render one catepilar :P, good video, thx

[@nischayajoon6185]

Sir, can I get the project Files, I am having trouble

[@Blendini]

If you can tell me what you're struggling with, I may be able to help. Alternatively you can email [e-mail] with your project file and I'll try to figure out the problem and send a working one back.

[@AshishSharma-yj1nb]

getting an issue with the box is going in up direction i tried everything please save my ass. its very problemetic

[@Blendini]

Hi there! Sorry for the delayed response. When it comes to the physics properties for your cube, Collision needs to be after Rigid Body. If that doesn't solve your issue, you can email me [blendiniyt(at)gmail.com] a copy of the file and I can take a look at it and hopefully get you a solution.
