NormalMap Problem: Artifacts appearing when exporting the texture

Urix · May 2018

Hello,

I have encountered this problem in Substance Painter when I export my normal map.

After baking it seems ok but when I export the normal map some artifacts seem to appear.

Any idea what could be causing this?
Thanks.

Probably lack of bit depth. If you aren't already, I'd suggest exporting out at 16bit. Also might be worth looking into dithering (I don't think this is an option in Substance Painter though) but Marmoset has a pretty good explanation of it: https://www.marmoset.co/posts/toolbag-baking-tutorial/ Under Best Results, at the bottom, Banding, Bit Depth and Dithering.

Good luck!

Thanks! Exporting out at 16bit went perfect.

Also thanks for the link, I'll defenetly make some tests baking on marmoset
