Collision plane with box not working (triangleMesh collider)

Discussions Support
#1

if you have two objects and both have triangulated colliders

  1. plane
  2. box
    collision in this case not working, box are falling through plane
    Is this a problem or standard behavior of physics?
    i’m do not remember but I guessing what in unity this works property.
    there are some options for continues collisions for tiny objects
#2

Triangle mesh from bullet physics library can be only static, it won’t work properly if mass is other than zero. Use convex hull instead

#3

Oh, thanks szamq.
I don’t knowed about this.

Did you looked on convex hull debug line? it’s looked little wierd, no?

#4

Triangle mesh should work for active objects. Can you provide a simple example scene ?

#5

I can’t remember if the vertex buffer has to be dynamic for it to work. My brain is mush.

#6

Can you provide a simple example scene ?
The scene is very simple. Floor and box both CollisionShape = TriangleMesh. And if I change type collider for one of them to other it’s work fine, but not TriangleMesh with TriangleMesh;
