I gave the new Basis compression a try with a couple image texture assets that I am for now preloading. For some reason, those Basis-compressed assets seem to be preventing the preview from loading. Removing the Basis compression fixes the issue. In the profiler I see this:
which if I’m understanding the profiler correctly those 2 assets are still getting loaded? I looked at the devtools network requests, and according to that those 2 assets were already loaded. I relaunched the preview in a different browser, but I’m getting the same results. I’m using the ASTC compression algorithm.
