1. Horrific Normal Baking Errors?

   

   Topic by Dan Powell · Apr 2015 · Home› Technical Talk

   Hi Polycount, Using XNormal to bake a Normal map, but I'm getting some horrifying smoothing errors and I don't know what's causing them. - My cage on the low poly mesh looks fine. Everything should be triangulated correctly. - UVs look fine to me. - Normals look fine on the High and Low poly. - Test bakes in 3DS Max look…

   As a whole it's not looking so bad now. Been gradually sorting stuff whilst making tea. Just a couple of little issues left: The octagon shape with the circlular extrusion might need a few more sides to help smooth it nicely. Couple of smoothing errors here - probably smoothing groups or too little geometry?

   I've got padding set to 8 at the moment. I've fixed most of the stuff. The remaining issues are where the UVs have just skewed for some odd reason - presumably because there were normal errors. I've got it open in Marmoset too (awesome work on that by the way!) :) Not solely relying on the 2D as that would be difficult to…

   Looks like pixel padding, not a bad thing (very good, in fact, helps with mipmapping). You could stand to have a lot more pixel padding, as too much is not a thing. Never look at a normal map in 2D to diagnose problems, apply it to your mesh and see what it actually looks like.

   Normals were flipped after resetting XForm. Getting better results but still some artefacts to clean up

   No puke colour anymore but still all sorts of weird artefacts

   I have the low but not the high - good shout. I'll give that a go now

   Those puke green colors are usually from inverted normals in the high poly. Have you reset xforms on both the low and high?

   Glad you got it sorted out! Keep on kicking ass.
