Normal Baking question

rxshardcore

I have a question about normal baking. I've created a low poly model and a high poly model. I tried
to bake my normal map in maya and in xnormal with some strange results

It is my first time baking normals from a high polymodel and i'm not sure if i do it right.

Do you have the "Discard back-faces hits" box ticked in xNormal?

Yup i did that.. someone else told me that is could be a problem with the casing of my low/high poly.. one of them is to big?..

So which one need to overlap the other one? the high or the low?

Your lowpoly should also be as close as possible to the surface of the high, not bigger, not smaller. Match it as accurately as possible.

Then, the issue is your ray distance or cage size. The closer your high and low line up, the smaller the ray distance, or smaller the cage can be. Try adjusting your ray distance settings if you are not baking with a cage in xnormal.
