Collision box ends up square instead of contoured.

I'm trying to make a particle system of hail bouncing off an umbrella.

I have the collision tag on the umbrella. And a Particle behavior with collision turned on on the hail ball

When I run the scene, the hail falls and things collide but the umbrella has a rectangular collision box.

The collision settings on the Physics behavior are set to "contour" for shape, but the collision box isn't countoured.

If I make the umbrell not independent I can see the countoured mesh, but then the collision doesn't work.

I could sware I was able to get this working previously but I don't know how. Is there a way to make a contoured collision box work?

Correct answer KJerryK

Okay, got it. I've something I have to do right now, but will get to it in a couple hours. In the meantime, I did a test with both in the same puppet and I see the same thing you're seeing. So right now it's a mystery.


Oh, I took a quick look, and made this one change in the rigging, and this is what I get

The only way I've tried it so far is to have the snow and object in separate files. Here's what that looks like.

    Thanks. I tried it with the hail in a sepparate puppet but the problem is the same. Could this have something to do with the last update Oct 2019?

    I looked at the physics playground example puppet here:Character Animator Examples and it seems like all the balls in that scene have square collision boxes.

    Awesome. So the key was to make the main group independent. Thank you so much!
