Yer i’m having massive problems with decimation master as well. At framestore we have recently started to use decimated meshes alot instead of dis maps, especially on environments, such as trees and rocks, and any object over 20 million ish crashes due to ram problems.Even though the ram never gets close to being used up.
This seems to be a pre-process problem as i can decimate objects at around 19 mil wihtout any issues. Also, pre process all does not seem to work at all anymore with multi hi poly sculpts.
I not a massive fan of having objects this highpoly if i can help it, but youre always asked to go a little higher if you can, and slicing objects always seems mess uvs about which means more work.
