High poly normal map looks weird on my low poly mesh

MoonManTV · Oct 2018

Hello,

How do I fix these kind of normal map errors, as I seem to get them all the time when I bake a high poly normal to my low poly mesh. Thus far I have tried it with xNormal and substance painter, with xNormal I have tried it with various different meshes.

FYI I use 3ds max's Subdivision Surface tool.

For proper assistance, please show us your highpoly, UVs, bake settings and resulting normal map. Also, are you using a cage?

Maybe jsut really low resolution and no straight UV shell? But yeah difficult to judge without seeing the UV and the low or high poly

At a glance, looks like a padding issue that's throwing those seam and bleeding errors but yeah as @Thanez said we need more info to drill down on this for you.

UVs,

I didn't use a cage.
And these are my baking settings, I have seperate materials setup on all seperate parts of the weapon and baked them all the same way.

This is in substance painter it only shows the current section im working on, the normal map however shows all the areas which I have made pictures of.

Straighten your UVs. Aliasing matters.

Increase the Dilation width setting.

seems like you have separate meshes? maybe try this:
give your meshes "NAME1_low", "NAME_high" (per mesh part, low for lowpoly high for highpoly

)
