Thanks for the report. I can also confirm this. I’ll note it in our internal bug report.
Update. I did notice that the IR will update eventually if you keep changing the texture. The first change had no effect but any texture change after that the IR updated as expected. Is this happening to you also?
Yeah so I kinda feel off the map for a bit there… Anyway, I tried reproducing this behavior in the latest daily and it regressed up to a point where all the material channels exhibit the same behavior.
Changing the texture after it gets “stuck” doesn’t update it either. You literally need to restart the IR to get the right texture to show up although that might be something that the newest build introduced.
