Hi,
here's my list of thing's I would like to see improved in 3.5 IPR mode:
1, This is probably the most important one - being able to run IPR inside of a viewport. 3ds Max UI is a bit clumsy, so it doesn't allow to dock things around much, and if you have VFB floating over your Max window, you constantly struggle for space. I can not even make viewport layout, and precisely put IPR VFB inside of one of empty viewports, because:
A, IPR size does not scale with window size, and...
B, VFB size is reset on every render.
Even if I was able to do that, I would still be wasting a lot of space having window header, and top and bottom VFB bar in there.
2, Light Cache - Running IPR in any kind of interior is so slow the IPR stops being interactive at all. It's equivalent of hitting F9 key manually each time. AFAIK Corona has worked around it by postponing secondary calculation to be parallel with first past, and reducing secondary GI accuracy to about 25% of the production render value. If you won't manage to do that, it would be at least good to give us option to override secondary GI for IPR only to brute force
3, Performance - I am running Max 2017 which should be bit better for interactive rendering, but despite V-Ray progressive having subsampling, update rate is around 0.5FPS. This could be improved to reach at least V-Ray RT CPU level.
4, When IPR runs, window size should define resolution of the IPR. Some people may not want that, so in the end there could end up being yet another switch, but in general it's better solution for vast majority of cases. If I have my production output set to 1920*1080, I definitely don't want to run IPR at that resolution, because it would completely kill the interactive feedback. Instead, I want to run it at something like 640*360, but constantly changing resolution setting between IPR and production resolution can get old really fast
Thanks
