Is this an antialiasing problem at all? Redshift Normal Map from Substance
-
Hello everyone, I am using textures exported from Substance 3D Painter and applying them to the couch object. I get ugly results probably caused by the Normal map, since when I significantly reduce its intensity (Height scale) or turn off the Normal map completely, the problem disappears. I'm not experienced with Redshift or texturing, so I tried randomly changing some values in Render Settings>Redshift>Sampling>Filter... or the Normal map texture setting... or even the Bump map node settings. In Bump Map attributes>Inputs>Advanced I tried to select Legacy Normal Map Technique and only then it was ok. However, I suspect that this is not the right procedure and I want to ask someone smart here, what would you try in such a case? Thanks for your time

Hi hang-single,
Thanks for the screenshots. It shows me something but not the why. I firmly believe that some results can be caused perhaps by several influences. Just guessing is not my MO. (If I would guess then: your Height Scale is too large, I would wonder if that fixes it)
https://stcineversityprod02.blob.core.windows.net/$web/Cineversity_Forum_Support/2023_Clips_DRS/20230917_RS3518_Keller_Legacy.mp4Please share a project folder with related textures for those kinds of questions. (Reduced to the problem, zipped and please via Dropbox, [Google, Apple, Adobe, Wetransfer is OK too, anything else hasn't been cleared [security].)
The improvements around version 3.5.11 or 3.5.12 for Normal mapping can be ignored and set to Legacy. Here is also to mention the Keller Algorithmus; see link. If Legacy works better, then it seems you found your setup.
Please have a look here:

All the best
