Just thought of an idea after I had played Gran Turismo on PSP. To save the framerate, they had a low resolution on the mirrors, and normal resolution on everything else. So I started to think on how to do this in Blender. My idea was to have a low resolution texture, but it didn’t make any difference at all. But still I think that it would be a great feature, and it would be great especially for car game makers. So now I wonder if you could change the resolution of realtime mirrors(or even better on the render to texture feature, while, if I’am not completely wrong, normal mirrors only supports one per scene.
