Photoshop...
There are several issues with meshes in POV-Ray and this is one of them...
and not the worst. At least black triangles can be photoshoped away.
Subdividing is a solution but then it's not always possible to keep the uv
vectors (Cinema 4D can do that but it's not exactly free). Christophe
Bouffartigue once made a patch that seemed to fix this problem.
Here are other issues you will meet at one time or another:
- using high radiosity settings on multi-layered, semi-transparent meshes
(such as hair) tend to darken them, sometimes turning the texture into pure
black. I never found a solution for this.
- under certain lighting conditions, interactions between parts of the mesh
give ugly results: lighting artifacts start shining through the edges of the
triangles (nice cracking effect) or in other places. Particularly, I have
ongoing problems with the eyebrows and lashes when used with certain hair
models in Millenium figures. I sometimes use uvmapper to remove eyebrows and
lashes, which fixes it but isn't a good solution for close-ups. This is why
the kid in the "Reach of the stars" picture is seen from behind...
-in Pov-Ray 3.5 using meshes and reflections can sometimes end up in an
infinite loop (a real plague when I was working on the WTC memorial
project). This seems to be fixed in 3.6 though.
