Thank you for clarifying that.

I've been experimenting with my own mesh macros, but I've encountered some
problems. The biggest one is about the uv_vectors in mesh2. See p.u.p.

My idea is to create a new format that combines the best from PCM and mesh2.
(It would not support bicubic_patches though.)
