Normal Map Banding Issues

[system]

Hello all!

I took a quick look around and didn’t find anything on this topic, so I’m here to ask about a “banding” issue when I export normal maps from ZBrush 4R2. (Please see the image, as it’s a little hard for me to explain.)

Whenever I export a normal map, no matter the settings (ie. tangent, adaptive, smoothUV), it looks like the mesh has been transposed onto the normal map. My mentor said it may be a round object problem, but we’re not entirely sure since we just switched to 4R2. I was curious if anyone with more 4R2 experience had encountered this problem and had any suggestions.

On a side note, exporting as a displacement map and plugging that into a bump map node seems to work better, but I don’t get as much clarity as I would like.

Thanks for your help!

Hi, did you ever figure out what the problem was? I’m having a similar issue (I think) but with texture maps showing some weird artifacts from the low-poly. My issue might just be that my low-poly and high-poly are too different, but that doesn’t look like the case for you so I’m interested to see if you find a solution. =)

Also, what program are you rendering in for your last image?
