Problems recording physics to IPO (Bugs?)

Hi,

Was wondering if anybody could shed some light on the problem I am having right now. I am creating a piece of animation whereby three tall blocks standing side by side would topple over and break apart into several shards.

How I was trying to achieve this is by doing a hand-animated topple of the blocks (I hand-animated it so that I can control the positional shearing of the blocks), and then as they hit the ground, I swap the frames in edit with a version of the blocks that are pre-shattered that would break on impact with the ground via the physics engine.

Now the problem is that, in the second animation segment using physics, I shattered the blocks by using a plane that has a displacement modifier. I would shove that plane into sections of the blocks, and hit W to use the boolean tools and difference. Then I would flip normals on that plane and get the other side. I did this multiple times on the blocks. Then I chucked the plane, and ran the physics and it did fine, shattering as I wanted it.

The problem starts when I record to IPO. The physics would play back, then when I go back to IPO for keyframed animation playback, all the shards are sticking together! Please help! I’ve attached a picture of the blocks. I get the feeling the problem has something to do with the shattering technique and the blocks are linked somehow.

Thanks in advance

Just to clear something up, the physics ran correctly when hitting P, but the recorded IPO was not, and the pieces were stuck together…

OK, well, I did the same thing in Blender 2.5 and now it works :slight_smile: Guess I have to change my mind about not switching yet…
