Re: Texturing a Multi-Piece Model 2004-08-04 - By ccoles_avengers

Ah, my dear James [ cool sounding name, by the way. :) ], I empathize
with you. I have been down a similar road myself. But there is an
appraoch you can take that will hopefully save you time and energy.
First of all, go through your model and look for all the objects that
you want to share one type of shader. Then group those objects
together and export them as an OBJ model. Then, import that same
model, but when prompted with the "OBJ Import Options" window, choose
the selection: "Grouping: Create Only One Object". This will now
bring those groups of objects into your scene as *one* object which
you can apply one shader to across all of them. You should then be
able to have the same proportions as the original shader across the
entire group.
Here is an example of a multiple-object model converted to a OBJ
object sharing the same exact shader. The first model (foreground) is
the original group. The second model (background) is the OBJ model.
Notice how the OBJ texture is continuous over the different shapes
where as the original group model has distortions and lacks continuity
of the shader when applied to each object.

But James, do note that if you need to move or animate one of the
objects within a group, then you will need to deal with that as a
*separate* object and shade it separately as well.
Well, I hope I am making sense. Just let me know if you would like to
have the CAR file to examine. Hope that helped.
Cheers.
