I thought I'd tell you to help narrow down where to look.

Sure it helped, at least gave some ideas to how avoid a crash in casezoppo wrote:I thought I'd tell you to help narrow down where to look.

Yes, normal maps should always be gamma 1.0; in fact any 32bpc bit file should be as well.Kalua wrote:Phong is not interfering in this case.jayroth2020 wrote:Kalua, what value is the phong tag set to? Cinema usually defaults to around 40 or so...
Actually playing with the gamma (from 2.2 to 1) actually fixxes the issue. Is there a guideline on how you should Normal maps be set? Some maps work better than others. Is there any issue I am not aware of?

Did you see the workaround above?CCIDgfx wrote:I just wanted to update that I went back to 2020.1.5-R4 and store render buffer is working. I just saw another person having the same issue so I know it's not my machine now.

Thank you so much dude =)zoppo wrote:I have the same issue and I don't intend to switch from R20 soon (lots of plugins ...).aoktar wrote:EDIT: It's an issue for R20, can't fix it. Why do you prefer R20?
The Live Viewer A/B view is not working, store render buffer is not working and this is a HUGE problem that should be dealt with.
Now, my friend useruser found a workaround, so Aoktar, I think this should be fixable in R20:
Enable "Lock resolution" and change the y-axis resolution to something other than 1:
That's it. You can change both values so they match, but the important one is the second one.
It does even work when you set it to 1.01 and leave the other at 1.
