Is there a way to export textures from blender for use in 3ds or maya(textures made entirely in blender)? how can I do it?
Are you talking procedurals or images? Procedurals, I don’t think so. Images would import the same, so I guess you are referreing to the procedurals.
I’d suggest copying the settings and modifying procedurals in the other app to resemble the blender one you made.
if your Blender texture is final, then you could bake the procedurals textures into the UV diffuse map of your model, it’s the only way I can see for now… once exported, the .3ds model will retain the original Blender textures merged into a single uv map.
