Saturation Blend Mode completely breaks the UV layout and layers below [7.4.3]

Report · Jan 23, 2023

Using Substance Painter 7.4.3 on Windows 10, this problem did not occur until I installed a new graphics card from a 1660 TI to a 3080

Simply using a layer with saturation blend mode causes the entire model UV to warp, whereas it used to blend the way it was intended to before installing the new GPU. I have the most up to date drivers and I double checked to make sure.

This does not happen with any other blend mode other than saturation.

The video attached demonstrates the issue. I find satuation layers to be incredibly useful and this bug completely disables my ability to create the materials I like.

I can see the problem in your video but have not been able to replicate it here.

I use Substance Painter version 8.3.0 and my GPU is an RTX3090 with NVidia Studio driver 516.94. What version of the driver are you using and have you tried reinstalling with NVidia's clean install option (which is under Advanced in the installation dialogue)?

Thanks for getting back to me! Unfortunately, this hasn't seemed to fix my issue.

I did a clean install of Studio Driver 528.24, restarted my computer, launched substance painter, an then added a layer and set it to saturation blend mode, and sadly got the same result.

It should be noted that I am using an older version of substance (7.4.3), as I do not own the newer versions because I had purchased it on steam.

Thanks again for getting back to me! Hoping some way can be found to resolve this issue.
