Horrible normals

Ryandec

So I have created my high poly mesh and I have a low poly that is uved, but still I get these horrible normal results using xnormal, I even tried using mud-box to bake but that wasn't any better, is it my low poly or could it be my uvs?

here is my scuplt

Could you post an image with the map applied to the low poly?

as u can see it looks awful

I dunno wheter its do to with my uvs or wheter its just a bad low poly or even me baking it wrong in xnormal, but I didnt try with mudbox and it still looked quite bad, it was slighty better..

It looks like some of your normals were flipped, you can normally find them on your low poly if you toggle the backface culling, but generally there is a button to make all normals face outward.

There are a lot of things making it look bad. Here is a list:

1) Hard edges without UV padding
2) Not an averaged projection, missing information in the gaps.
3) No super sampling or anti aliasing
4) Distorted projection envelope causing missed projections inside concave areas of mesh.

If you watch all three of these videos you should have a good handle on baking:
