I’m doing a bunch of animations and ran into something. I’m doing a lot of preview renders and switching Raytracing & Shadows off and such is real easy, but what helps a lot as well is to switch of all the subsurface modifiers.
Since there’s no global option in blender internal I wrote a little script that does it for me. All it does is it switches the Render & 3D view of each subsurf modifier it can find. Be aware… all it does is switch, so if you have some switched on and some switched off… That situation will simply reverse.
Also: It only runs in the current cvs, not in the official 2.42a release!
