When trying to put a mesh2 into a mesh_camera instead of a regular mesh, POVray
aborts on the line containing vertex_vectors with "Parse Error: No triangles in
triangle mesh."
Putting a triangle into mesh2 seems to work.
Writing mesh42 instead of mesh2 causes a parsing error at this point already.
Using mesh2 objects for regular objects works fine, though.
Please tell me if you need additional information.
