Transferring materials made in Cycles Render to Blender Game Engine I have a question about importing objects painted in cycles render to a blender game engine file. 

I've just finished my model and want to put it in a game. I textured, rigged and animated it in the cycles render. When I switch to the blender game engine, everything works fine, but my model's textures and material didn't transfer over. Do I have to texture it again in blender's game engine or can I just import the model into a blender game engine file?
Cycles and the BGE don't share the same (or even remotely similar) material systems, and the materials are not transferable between engines. That means you will have to create a new material when switching engines. However, if you have any image textures or any other non-procedural data you can reuse them, you will just have to set up the materials to use the texture.
