Maya - Normal Baking help

Marshkin

Hey guys,
I've poked around on the forums for an answer to this already, but I can't seem to get this to work right, or rather, to figure out exactly what I'm doing wrong.

The short and sweet of it is that when I bake my HP down to my LP in Maya, everything works fine except for one area, where it distorts really badly when I rotate the camera:

Example;


Looking at the normal map, I can see exactly where it is breaking

How do I fix this/prevent it from happening?

The High poly model looks okay... (I think)


Low Poly;


and last but not least, settings;



Help?

Hm, looks like the area in question has quite a few 90 degree angles, and from what i've seen people saying on these forums, and from a couple of vids on youtube, Maya's normal-baker (or maybe it's the UV editor) doesn't like 90 degree edges.

Try adding a bevel to the top and bottom of those 'walls' around that depression, on the low-poly version

It looks like you've correctly split the uvs with hard edges there. If you box-select vertices in the problem area, are there any duplicates?

Edit: You can also keep that interior as a single shell mapped straight, think of it as unrolling a ring.

There isn't enough detail in the low poly curvature to follow high poly. You will need to add edge loops to the circle to make it more...circular.
