Hi Roland,
Thanks for the response.
I see what you are getting at, however, does this work for a
BitmapFileMaterial?
Let me try again to explain what I'm doing.
I have 1 .obj file (i.e. teapot_1.obj) ...
I have several different bipmap files (i.e. teapot_1.jpg,
teapot_2.jpg) that I can swap around when I load initially (removed
texture & mtl info in .obj file) as such:
= Obj.load("assetts/teapot_1.obj",{material:texture3});
or
= Obj.load("assetts/teapot_1.obj",{material:texture2});
or
= Obj.load("assetts/teapot_1.obj",{material:texture1});
They all load fine because I coordinated the UV mapping for all to the
object.
Is there a way to break apart the Obj.load such that I load the obj
first:
= Obj.load("assetts/teapot_1.obj")
and then load textureX (i.e. teapot_1.jpg) with seperate "command"?
I thought I saw a basic example where it was done in 2 steps but I
can't find the example now ...
