Mesh wont use Prim physics from file

[AaronN117]

I'm insanely confused as to why it wont work, but my mesh refuses most times to use Prim for physics. I made a building mesh separated into about 11 objects. They are all exported into the final .dae file. I made a custom physics mesh for the building, so I can walk through doors and the sort. I tried everything from triangle method, to analyzing the physics shape. The only time the prim option ever showed up correctly and worked, was when the physics mesh was analyzed and simplified horrendously. By then it was impossible to walk into the building at that point. I must have uploaded 100 different times trying to get this working.

I don't know if my physics mesh is wrong and not uploading correctly with the mesh. Funny thing is, the physics mesh would work correctly at some point, but after necessary edits to the physics mesh in blender, the physics started not working again. I don't understand why, if it is, blender may be mucking up the export.

If you have 11 objects in your dae file, you will need 11 objects in your physics dae file as well. With each physics shape matches the bounding box dimensions of it's visual counter part. 

The thing is, if you don't specify a physics mesh in the Importer, the Prim Type option won't be available for these meshes. Which would be 10 out of the 11 meshes in your final dae file.

Following this naming convention on the objects names inside your modeling app, makes sure that the physics shapes are sorted correctly during import.

This post pretty much explains what you need to do. For each of your house pieces you need a separate physics piece THAT IS NAMED CORRECTLY so that the uploader knows which physics model goes with which piece.
