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?

$\begingroup$ Yes, is there a way to do it here? Or I coud just send you the file? $\endgroup$– 8paulaCommented Mar 8, 2022 at 19:42

1$\begingroup$ remove all the useless object and share the file here (upload and copy paste the URL it will generate): pasteall.org/blend $\endgroup$– moonbootsCommented Mar 8, 2022 at 19:57

$\begingroup$ So I am trying to make the tiny ball fall on the shoe at 230 frame but I don't know how $\endgroup$– 8paulaCommented Mar 9, 2022 at 9:44

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)
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:
one frame later set keyframe on "unchecked":
result:

$\begingroup$ 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. $\endgroup$– 8paulaCommented Mar 9, 2022 at 10:22

1$\begingroup$ 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. $\endgroup$– ChrisCommented Mar 9, 2022 at 10:51

$\begingroup$ 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! $\endgroup$– 8paulaCommented Mar 9, 2022 at 12:08

$\begingroup$ But I still don't know how to start the rigid body simulation from a specific frame. $\endgroup$– 8paulaCommented Mar 9, 2022 at 13:00

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.

$\begingroup$ I did that and it's not working, and I don't know why. $\endgroup$– 8paulaCommented Mar 8, 2022 at 19:43

$\begingroup$ Make sure the first dropdown is set to active and not passive. (Under the "Type" dropdown, right at the top) $\endgroup$ Commented Mar 8, 2022 at 19:44

$\begingroup$ Under the scene properties tab, (It looks like a water drop with two circles) Make sure both gravity and rigid body world are turned on. $\endgroup$ Commented Mar 8, 2022 at 19:47

$\begingroup$ it's checked. I tried both passive and active - nothing works. $\endgroup$– 8paulaCommented Mar 8, 2022 at 19:50
