ID Map Baking. Problem. Irregular color.

[Corthus]

Hello everyone

I have a weird problem.  I Want to try bake, ID map in substance painter, and after baking i've got this effect...

Got some weird difference between colors. Blur, in some places color go further than should be, in some places disappear. This cause problem when i want to use color selection.

I try adjust output LVL, Hardness and Tolerance but it did not give the intended effect.

When i bake ID map i have Antyaliasing set to 0.

And i dunno how to repair this... Where the problem is? It's normal map, or i do something wrong during baking?
