The Driver version you’re using 7602 is equivalent to 576.02, please revert make to 572.47. It is currently a known issue with 576.02, and it is best to avoid the driver version for now. Thank you.
I installed the 572.47 driver (I could only find the game ready version), but unfortunately this didn’t help. It’s still changing colours when I press render.
No, “smooth” mode is not on. Once I either hit “render” or “accumulate F4” the pathway goes almost white. The material is “Road Surface 29” from the D5 library. I’ve tried a few other materials, but it seems to happen no matter what I use on this pathway.
It’s almost like the material is losing its base color map when rendering.
Please send the entire folder of your project. If only the .drs file is sent, we are unable to open it, which may cause some issues. I apologize, I wasn’t able to mention it beforehand.
I just tested your file. It seems that this particular issue persists because of Path Tracing, and it is only affecting the specific Material Road Surface 29
It seems like there is something wrong with how Road Surface 29 is calculated with Path Tracing enabled on this particular file (replicating it in a demo file does not yield the same result). We will be investigating this issue.
Our team just confirmed that this is currently a known issue when materials are set to have a Roughness of more than 0.5, and at the same time, Path Tracing is enabled. This issue will be addressed in subsequent releases. Thank you.
Note: Some materials, despite having a roughness of more than 0.5, will not yield the same results (completely discoloured) compared to others. Some will behave abnormally when their normal colour is set to a different option other than the default one.
