Hello, I have done some tests with new version, I think it is pretty close to stabile and production use, I have found few things that needs to be solved before serious use of IR and this version in everyday usage.
Some bugs I have encountered (some of them are maybe mentioned here already but I had to point it again cause they are making this unusable in production):
HDRI - Changes does not update in IR window
Post effects in IR window reset to default after changing for example light intensity in corona light or moving object and for many other situations.
Override materials gives some errors in preview, some object does not display correctly (if I put white material in override some object remains grey).
Other stuff that are maybe not bugs but would be nice to have are:
IR window size(resolution) not dependent on output size
Option to stack ir view to side by side view in viewport or any other viewport window (Like in 3DS max)
I will test more these days and write down my thoughts. Beside these I think developers have done great job in this version and it is a huge step forward. Good luck in future work guys :)
