Try downsampling the HDR cubemap to even lower resolution, e.g. 64x64. It shouldn't affect diffuse lighting much, but should help reduce fireflies. Are there any console errors? If Unity fails to compile any script in the project, it will prevent it from compiling everything else, including Bakery. Pink skybox: maybe the developer didn't properly import Bakery? Do they have Assets/Bakery/ftSkybox.shader and is it used on the skybox (in case you used Bakery skybox shader)? There might be a bug with GI VRAM optimization I didn't manage to track yet due to not having any scenes where it can be reproduced Not exactly sure, but maybe reducing Max Resolution (to e.g. 2048 or 1024) will help.
