So, the title pretty much sums it up. I have a custom mesh I've imported into T3D, and I set the collision to "visible mesh" (I intend to create proper collision meshes at a later time, but this is just for set-up/mock-up work). I notice that I can rotate the model how ever I want and collision works fine. However, when I scale it, the collision breaks and my character runs right through it. I have multiple duplicates of the same object in my scene right now, and the ones kept at, or very near original size work fine. The ones I've scaled notably larger lose their collision.
Is there a way to fix this, or kind of "refresh" the collision to work on the larger mesh size on those objects?
And while I'm at it, a second question, can you have multiple collision meshes per object? Since collision meshes need to be convex, it would make it difficult to create a convincing looking collision mesh for an object that has an overhang or is otherwise concave in shape, without the player hitting an "invisible wall".
