Is there a way to connect a low poly object with a high poly object linked from another blend file, that is only interchanged on rendering?
Example: In the viewport I have my low_cube.001. It is connected somehow to high_cube.001 in the high_cube.blend. In the viewport there will always be low_cube.001. On rendering the scene with Cycles, there should be high_cube.001 only.
Is there an "artists" way? If not, is there a way I can interchange objects with Python, somehow transfer the high poly object into the render engine?
EDIT: Regarding Python, I don't need a finished piece of code completely worked out, just some directions or ideas would be great alreay!
