I have run into one problem. I get a:

error: Attempt to malloc zero size block (File: parse.c Line: 4385).

  This line is inside the Parse_Mesh() function and is the following:

  Object->Data->UVCoords = (UV_VECT *)POV_MALLOC(number_of_uvcoords*sizeof(UV_VECT),
"triangle mesh data");

  It unconditionally allocates space for uv-coordinates even if
number_of_uvcoords is 0 (as it is in my case where I only create triangles
with the tesselation function).

  Shouldn't it be enclosed in an if(number_of_uvcoords)?
  Will I break something if I add that condition?

  Why it doesn't crash with regular meshes (without uv-coordinates)?
