Jagged Edges In Substance When I apply a seemingly good normal Map

jamecz

I'm modeling a toy to practice baking maps and I finally got a good one out of xnormal after a ton of tries. The red object is the standard low poly with textures on.


      
However, when I render it, I get jagged edges. The same thing happens when I put the normals in substance
painter... Any solutions to this problem?
        


Any help is greatly appreciated!

There are several things to point out;

1 - try to lay out your UV islands with straightened border edges where possible. This will minimise aliasing.

2 - increase the segments on your rounded shapes. If too low then the bake projection is trying to match a low poly to a high poly that has a much more rounded surface, resulting in a very different silhouette.. What you're seeing is often referred to as 'waviness'. See the sticky thread on top here.

Looks like the red channel of the normal map is inverted - rare, people usually have their green inverted

Thanks! I eventually got the normals on the head all figured (just a matter of changing the normal map format in Painter) out but the curviness of the borders on the body pieces causes weird pins. I'll try and straighten the borders out

Odd, I guess I just gotta bake again

Why not bake in substance?  It's faster and there's less mucking about

I started baking in substance about a week after you commented. SO MUCH BETTER than xnormal.
