    We are working on a project for the Oculus Quest/PC VR, recently noticed ASTC texture compression is recommended in the Oculus Documentation for Unity so we switched to it. As soon as we switched to it, lightmaps seem to bake in a red tone. Switching back from ASTC to anything else in the build settings window allows lightmaps to bake correctly again.

    I am submitting a bug report as I write this but it keeps failing because the bug reporter sometimes errors out with 'bad gateway' or something. I feel like a full-time QA tester for Unity lately with the amount of bugs I have submitted. oosh.PNG

    Thanks for reporting the issue. I assume you are using high quality lightmap encoding, right? For the time being, you can use RGB9e5 compression, if you require HDR intensities.

    I was having a mess around with the saved lightmap formats and that was the one that worked so thanks for the suggestion, hopefully this issue can be fixed in an upcoming release
