Is there a way to precompile/preload all shader variants used by the main scene in this project? I'm unable to use the preview mode yet, since the Editor constantly hangs for up to a minute to load shader variants. Maybe creating a shader variant collection can help with that? The variant loading itself is less than a half of the time in the stalls, though - it looks like updates to all systems pile up while editor loads the variants, and cause a humongous spike on next frame, with Game.Update taking 3000ms+ and requiring collection of 30mb+ by GC. Edit: Thankfully, that's not a repeating issue and pushing through the level blindly for a while seemed to force loading of most variants for me. Still, I'd like to know what best practices for avoiding this issue are - it's occasionally an inconvenience on my project too.
