Hello all,
I've run into a problem working on a scene with 177 materials, and a total of about 540 textures. I was previously having trouble (as you can imagine) with VRAM consumption and so started switching all greyscale textures to float, and then all RGB textures to BC1 compression, RGBA to BC3 and HDRi to BC6. About a third of all textures are greyscale, the overwhelming majority of the rest is simple RGB.
I was about halfway switching the RGB textures over to BC1 compression when I started getting recurring crashes. In between crashes and with frequent saves I managed to get two thirds of the RGB textures switched over to BC1 compression. Now the file is very unstable, and Octane hangs while trying to generate materials.
The VRAM savings are very impressive, I'd like to avoid having to remove the compression if possible - is this inherent in using compressed textures or is a workaround possible ?
Thanks,
Valentin
