Normals Issue

Moltar

Hi guys. Retexturing my gameboy but im having a few problems with my normal map during renders. For some reason Xnormals creates zigzags across some of my normal edges, it's never done this before and I've no idea what's causing it.

I checked my UVs, they are fine. Settings in xnormals is good also.

Maybe someone can help me out? (the large space in the Normal map is were the cartridge goes, im texturing it separate then masking it back in later)

Straighten the edges of your UV's, render the NM at a higher resolution or increase the size of your bevels. Any of these should solve it.

Moltar

Thanks Scruples. I relaxed some Uvs and made some minor adjustments. Problem seems to have been fixed.

Quack!

Those zig zags are on the edge of your UV islands. They are being dilated outwards because of padding. The true fix is to figure out why you had poor aliasing on your UV edges. This often boils down to poor anti-aliasing in the render. The suggested 'fixes' will only mask the problem rather then fix it.

Moltar

Any suggestions as to what might cause the problem, Quack?

Quack!

Did you use a high anti-aliasing value?

Moltar

yes, 4x

Moltar

Quack!

Hmmm, that is very odd. Anti-aliasing should fix this, so if it isn't then there are some weird things happening that I can't diagnose without seeing the files. You can post your files if you would like or just hope it doesn't happen again!

This is the first time it's ever done this, I've always maintained the same output settings... It is odd. Im re-texturing an old model for my portfolio ( https://www.artstation.com/artwork/gameboy-pocket ) Maybe, just maybe it's something to do with the Obj files.

Thanks for you help though, im sure this is just a one off.

1. Straighten your UVs, this should fix it.
2. You will never something as small as a gameboy from this close in an actual case.
3. 8k ?!

Quack!

Their Uv's look straight to me?

Obscura

Then take a look again Quack. They are not completely straight Theres a slight bending on a lot of them.

1. This has nothing to do with straight or slightly bent UVs
2. What?
3. Read the first suggestion.

This seems to be an issue with Xnormals, specifically during the dilating process. I just baked my normals in substance painter, they came out fine.
