[Max] Daily Builds / Re: Corona Renderer 6 for 3ds Max - Daily Builds Discussion
« on: 2020-08-21, 10:26:22 »Hi. Apologies if this has already been discussed...Hi,
There seems to be an issue with the noise level when using regions.
I do a render, which takes 15 mins or so, but when I do a region the noise level says around 4.5% and the estimated render time is 45+ minutes... It's obviously getting confused with the noise in the non-rendering areas...
Is this replicable, understandable?
Many thanks. I'm using Daily Build 21 July 2020.
EDIT: It seems this problem only persists when the full render processes a bit early on, and then during the render I add the regions. If it's rendering with regions from the beginning (ie; from a clear VFB) then it works as expected/properly.
I've just been testing this here and it seems to work as expected for me, if I add the region after the render has started it takes roughly the same amount of passes to converge to the same noise level without taking the extra time you are describing.
Would you,
1) Be able to install v6 RC3 and try it in this version? IIRC we also fixed another bug you mentioned in this version :) (You can set the bitmap tiling mode to clamped, in order to fix the artifacts you reported)
2) If the issue is still reproduceable in RC3 can you please archive and send the scene to us with some specific reproduction steps?
Instructions on how to do this are in my signature.
Thanks,
Rowan
Thank you so much Rowan.
Sorry to be a pain, it seems to be working as expected again (in RC3 at least) :) So thanks again.
However, I'm still struggling with the bump mapping issue... I tried with RC3 and changed all the bump map textures to 'Clamp' and the problem persists/is worse.
What exactly is this clamping? Should it be applied to all bump textures? Or all textures? Or only textures that I don't want repeating?
The bumps are often plugged into tri-planar nodes, which seems to be the culprit (as discussed earlier)
Please see attached screengrab from RC3 with clamping set to all bump map textures...
