Why can Redshift render giant scenes with their “Out of core” technology then, if memory would be such a big problem??
Its definitly doable. Because others do it already.
And who says that the engine has to run at the same time? Why not shutting the engine down and use all the GPU power for baking?
Or Use a second GPU for baking…
I have 3 GTX980 in my PC and i do heavy scene Renderings without any problems… since almost 3 years now.
Its just a question of will.
