Willian Padovani Germano f6ff9ec608 Scripts updated:
- Jean-Michel Soler: 1) paths import -- ai module; 2) tex2uvbaker;
- Campbell Barton: obj exporter.

BPython:
- Campbell also provided a patch (+docs) to add shader data access to Blender.Material.

Again, thanks guys and sorry for the long delay.

# Blender.Material module and the Material PyObject
"""
The Blender.Material submodule.
B{New}: access to shader data.
Material
========
This module provides access to B{Material} objects in Blender.
Example::
import Blender
from Blender import Material
mat = Material.New('newMat') # create a new Material called 'newMat'
print mat.rgbCol # print its rgb color triplet sequence
mat.rgbCol = [0.8, 0.2, 0.2] # change its color
mat.setAlpha(0.2) # mat.alpha = 0.2 -- almost transparent
mat.emit = 0.7 # equivalent to mat.setEmit(0.8)
mat.mode |= Material.Modes.ZTRANSP # turn on Z-Buffer transparency
mat.setName('RedBansheeSkin') # change its name
mat.setAdd(0.8) # make it glow
mat.setMode('Halo') # turn 'Halo' "on" and all others "off"
@type Modes: readonly dictionary
@var Modes: The available Material Modes.
- TRACEABLE - Make Material visible for shadow lamps.
- SHADOW - Enable Material for shadows.
- SHADELESS - Make Material insensitive to light or shadow.
- WIRE - Render only the edges of faces.
- VCOL_LIGHT - Add vertex colors as extra light.
- VCOL_PAINT - Replace basic colors with vertex colors.
- HALO - Render as a halo.
- ZTRANSP - Z-buffer transparent faces.
- ZINVERT - Render with inverted Z-buffer.
- - HALORINGS - Render rings over the basic halo.
- ENV - Do not render Material.
- - HALOLINES - Render star shaped lines over the basic halo.
- ONLYSHADOW - Let alpha be determined on the degree of shadow.
- - HALOXALPHA - Use extreme alpha.
- TEXFACE - UV-Editor assigned texture gives color and texture info
for faces.
- - HALOSTAR - Render halo as a star.
- NOMIST - Set the Material insensitive to mist.
- - HALOSHADED - Let halo receive light.
- HALOTEX - Give halo a texture.
- HALOPUNO - Use the vertex normal to specify the dimension of the halo.
- HALOFLARE - Render halo as a lens flare.
- RAYMIRROR - Enables raytracing for mirror reflection rendering.
- RAYTRANSP - Enables raytracing for transparency rendering.
@warn: Some Modes are only available when the 'Halo' mode is I{off} and
others only when it is I{on}. But these two subsets of modes share the same
numerical values in their Blender C #defines. So, for example, if 'Halo' is
on, then 'NoMist' is actually interpreted as 'HaloShaded'. We marked all
such possibilities in the Modes dict below: each halo-related mode that
uses an already taken value is preceded by "-" and appear below the normal
mode which also uses that value.
@type Shaders: readonly dictionary
@var Shaders: The available Material Shaders.
- DIFFUSE_LAMBERT - Make Material use the lambert diffuse shader.
- DIFFUSE_ORENNAYAR - Make Material use the orennayar diffuse shader.
- DIFFUSE_TOON - Make Material use the toon diffuse shader.
- DIFFUSE_MINNAERT - Make Material use the minnaert diffuse shader.
- SPEC_COOKTORR - Make Material use the cooktorr specular shader.
- SPEC_PHONG - Make Material use the phong specular shader.
- SPEC_BLINN - Make Material use the blinn specular shader.
- SPEC_TOON - Make Material use the toon specular shader.
- SPEC_WARDISO - Make Material use the wardiso specular shader.
