blender vs. maya collision

As a test I made a box in blender, extruded and scaled it into an open top box. Then I did the same in maya8.5. Imported both into Unity, put a box collider component on each and made spheres with ridgid bodies to drop into (onto) them.

The sphere over the blender box dropped down into the box while the sphere over the maya box bounced off the top.

Can anyone explain why the extruded maya model doesn’t work as a container?

Just curious.

Bouncing off the top is what I would expect from a box collider. Did you try a mesh collider?

duh… I should use the box to hide my brain.

I wonder why it worked differently with a blender file, though. One of those mysteries?

Anyway, thanks for pointing that out.
