Hi,
Not sure if it's a bug, so much as an unsupported texture?
But I've noticed since upgrading to the latest daily (8th Jan 2021, or maybe the one previous) that I get a LOT of crashes. I think I've boiled this down to materials that are using 'composite' maps.
I've attached a screenshot of the offending material set-up (it's from a purchased model, I didn't choose to use composite). The crash happens after a second launching of the IR. By this I mean the IR works fine once, I stop it, start it again and then I get the crash.
Scene is also attached (without materials, I can archive it if you want?)
Let me know how you go. Cheers,
