hey the once in a while curios tech question: do you guys DXT your distance values? Never experimented with texture compression whatsoever.

i think we did when we also stored explicit normals; when we do central differencing of sdf to get normals on the fly, i think we don't compress. i dont recall which one we're currently doing :) it's been a few years since i did gfx... need to ask

Distances are U8, I never got direct rendering of BC distances to look smooth enough, we do BC compress per voxel colour though

Interesting. Never tried it. ASTC looks good but no meaningful hw support.
