Collision box ends up square instead of contoured.

Question

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?

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.
