Yes, making a new Blender file. So if I have a scene where there’s a lot of assets and the poly count is high, I have a lot of textures, etc, I kick off a render and my video card brings up the out of memory error, what I usually do is I render in a totally new file. So I open a new .blend, go to file and link and I link all my assets to this file and there I do the render. With the data linked in the memory consumption drops down a lot and my video card starts the engines and renders away.
As far as I can remember, there isn’t a lesson on CG Cookie about optimization. We have focused on optimization in collabs, so maybe if you’re willing to watch any of the collabs 2020 and 2021 you may find some gold nuggets in there:
