Oops, that was a bit embarrassing… Anyway, thanks for the info 
I actually got to implement the changes I talked about a while back( well, some of them), and I don’t need one of the Voxel grids anymore, so 512 Mb less right there. The only thing was that I had to give up emissive materials , but that’s unacceptable, so I need to add a few more bits on the Voxel grid, and that’s gonna increase memory usage.
EDIT: Solved it, wasn’t compiling some files
