Normal Map Artifacts (Xnormal)

jocose · Jan 2010

Hey everyone,

I just baked a model in Xnormal and I am getting some subtle artificats on some parts of my model. Does anyone know what's causing this?

turn AA on?

Needs more UV space

Yeah - those look like actual pixels, not artifacts. More. More pixels.

I don't think he's talking about the pixellation of the details, I think he's talking about the long greyish streaks along the surface?
Not sure though.

what Mop said,

2. does the surface appear smooth on the normalmap itself, or does it look like it contains the barely visible artifacts too?

Those subtle artifacts would be pixels

So yeah, aa and texture space are important factors here. AA can only do so much without ruining the details when you have too little texture space, but if you haven't tried it yet, that'd be a first step.

edit: ah, the wisdom of opening a tab and posting in it a few hours later.
I assumed the grey streaks were my screen/compression.
Anyway, it would help if the OP could be more clear.

Given the smooth look, it just looks like another piece of geometry in the scene to me. And it's not subtle. I like the sound of artificats though.
