Hi,
I was trying to get some 3d signs objects to emit light in the night
(not the whole object, just the number/letters part of the surface). The
problem is I cannot create a .ac file with multiple textures; that way I
cannot have a first texture with the proper sign image and a second
texture layer with the emissivity informations. I only get a .ac file
with a single texture.
Which technique could be used to achieve such a visual effect? Should I
consider using some other 3d file format for FGFS? .obj format seems to
have no support for multiple textures either. Any suggestion?
Roberto
