TVPhysics CreateStaticMeshBody chokes on some models

[Craigomatic]

Occasionally we will find that certain models cause the TVPhysics.CreateStaticMeshBody call to hang indefinately. It doesn't throw an exception, just gets to that call and sits there.

Code:

physicsID = Core.Physics.CreateStaticMeshBody(theMesh);

I can provide a model that causes it to fail if that will help?

What you want to do is check your debug, make sure the mesh is not empty, and the file you were trying to load into the mesh actually got loaded. Perhaps you could also post the mesh. Be great if your mesh is in .x text format, as I can read such file to see what's wrong.

Everything loads correctly and there isn't an error in the log file. Physics is actually only applied when the app goes into a certain mode. The model (pool table) shows up as expected prior to this mode being activated.

After the mode is activated the CPU is pegged at 100%. It seems like the CreateStaticMeshBody algorithm is getting jammed.

The forum doesn't want to let me attach ("upload folder full") so here's a link to the model: http://rapidshare.com/files/114755390/pool_table.zip.html

i too have noticed this. it especially happens if there is a void area in the mesh (eg terrain with hole punched), or if the mesh has groups of triaingles not touching, but single group.

I'll test this model out and see what I can find.

Actually, I notice that if you have a mesh with coincidental verticies (multiple verticies with the exact same position), the physics engine does not function right. One such object is This Cone. I've tested it and it crashes when used as a dynamic body. Don't know if it crashes as a static body.

Well there is a Optimize parameter in CreateMeshBody.
Maybe try both ways, see if one works better than the other. The Optimize is maybe not working for several meshes. We can't control this though, it's done by Newton directly.
