That's the part I'm having trouble with...

I've sussed out how to export the textures from blender now, this auto
updates the models reference to these images on export. However....

1. The OBJ file contains code for a few references such as:
usemtl <id_of_texture_used_in_mtl_file>

2. This should then be looked up in the MTL file example:
newmtl <material_name_used_in_blender>
Ns <some numbers>
Ka <some numbers>
Kd <some numbers>
Ks <some numbers>
Ni <some numbers>
d <some numbers>
illum 2
map_Kd <file name to texture.jpg>

Thus linking the texture file to the MTL file and the MTL file is the lookup
for the OBJ file...

For me at the moment, broomstick throws an error of:
*ObjParser MTL LOAD ERROR: unable to load .mtl file*
*
*
*
TypeError: Error #1009: Cannot access a property or method of a null object
reference.

I have both the OBJ, MTL and texture jpegs at the root with the swf, so not
sure why there is a problem with this.

I have no examples to work from where an MTL file is used so am kind of
winging it at the moment. The EmbedParseDataTest with the examples of
broomstick when using the "assets/models/turtle.obj" which does have an MTL
file with it compiles as a blank.

So at a guess, I think it's on a to do or is broken at the moment.
