speed up render times just for lights setting up?

I’m trying to get my lighting right but the render times are just brutal…takes too long to see the results of the render.

is there a way I can make all the objects have no more CPU overhead than necessary just so that I can get my lights and shadows how I like?

dunno if I need to dupe the scene, make everything solid and gray, get my lights right, then import them into the “real” scene?

thank you for any suggestions!

You’ve probably been at blender for a while raycat, judging by when you joined here - but anyway I’ll give you my workflow if it helps…

For heavy scenes I will render just certain layers - if it’s a room, I will just render the room with a single object in it, then as the lighting improves the way I want it, I will then move onto engabling other layers to test them. Then do the full render when all looks well. Reducing Subsurf for the render can speed up things drematically - might not look great, but if you’re just setting up the lights/shadow/mood, then who cares about the details. I guess it really depends on what your scene is though. :wink:

thanks for sharing, Jay

You can also try turning off Ray tracing and Shadows under the Shading rollout of the Render TAB. Disable anit-alias, render at half-size. Turn off those soft shadows you may have on your lights. Under Sampling just use 1.0 for sample and 1.0 for soft size. Set all reflection/mirror materials to use 1 ray bounce.
