Maya uses OBJ's UV's to generate seams, some people complained that models imported from blender didnt work well in maya.
It was faster to write every faces UV (without doing a remove doubles), but sharing UV coords makes smaller files and might also be more efficient in other applications.
3ds_import - added option to disable recursive image searching (could be slow somtimes)
export_obj - when making group/object names only use both object and mesh name when they differ.
weightpaint_clean, weightpaint_grow_shrink - minor updates.
Render.py - own error in epydocs.
- Dont allow it to apply the matrix twice to a linked-dupe. (Same as Apply Loc/Size/Rot)
- Make sure that the source object is active, not just the first selected object.
- Use Mesh instead of NMesh.
- use mesh.transform(mat) rather then vert by vert vec*mat
Other scripts had pupBlock changes for better layout.
Minor changes to radiosity_export, updated to work with the new API (vertexColors MTFace)
obdatacopier - was getting the selection but not using it. made it ignore some read only properties.
BPyMesh - minor change: use face iterator rather then making a tuple()
import_obj - comments, docstring additions, cleanup.
OBJ export: -renamed export_obj
faster edge exporting (use edges LOOSE flag rather then finding zero face user edges)
check for file before overwriting
use object iterators
