I have a problem with my animation. I have two objects and I have already made an animation for the first one - it's falling down and bouncing - I made it manually. Then I want another object to fall on the first one and I want to use a rigid body simulation, but then something is really wrong and then the second object is not falling at all or moving somewhere else without any reason. I have tried applying scale, what should I do?

i assume, you want to use sphere.003:

first, you should always apply scale if you use that object in a simulation: (do for shoe + sphere)

enter image description here

second: turn off animated on your sphere (because animated means: does not participate in rigid body simulation but will be animated manually by keyframes)

third: change collision shape to mesh for shoe:

else it won't fall properly on the shoe.

How to start rigid body animation from a frame:

set keyframe on checked "animated" one frame before it should start:

enter image description here

one frame later set keyframe on "unchecked":

  • Thank you for your answer. Applying scale only messed up the materials on the object, but the ball in not falling down anyway. How to make it start falling at 230 frames? It only falls if I make a new ball and start it on the first frame, then when I make any changes is completely stuck where it was. – 8paula Mar 09 '22 at 10:22

    Then you can scale your texture as well with the mapping texture node. Change the begin animation to frame 1. then start the animation, you can change it back later to 9. – Chris Mar 09 '22 at 10:51
  • no, It doesn't work – 8paula Mar 09 '22 at 11:46
  • ok, it worked!!! So what I was doing wrong was applying the scale once, but I have to do it before every change - now - it works. Thank you so much! – 8paula Mar 09 '22 at 12:08
  • But I still don't know how to start the rigid body simulation from a specific frame. – 8paula Mar 09 '22 at 13:00
  • I want the ball to start falling at 230 frame, after the shoe is on the ground already. – 8paula Mar 09 '22 at 13:05
  • I updated my answer – Chris Mar 09 '22 at 13:47

Select the object you want to have the rigid body. Open the physics tab and click the option that says "Rigid Body" and your object should use rigid body physics.
