GPU lightmass broken

Gpu lightmass does not show any progress bars when show progress bars is enabled, does not show a preview, instead showing up as black until built, and refuses to bake any form of stationary light

Posting for visibility, the last part sounds a lot like the issue I’ve been having here.

Just to check, do your stationary lights still bake indirect, or do they not bake anything at all? I’ve also never seen progress bars and the preview seems very unreliable (it shows maybe 1/20 times). Also, were you able to get the gpu lightmass to work in preview builds before the 4.26 release?

I did not try in preview, Indirect and static bake perfectly.

You have to turn on Enable virtual texture support and enable virtual texture lightmass in project setting,it works for me
