Yellow and green areas in normal map texture after baking

Help me please to solve the bake problem.
I have strange yelow and green areas on normal maps texture. If I render it the areas looks black (screenshots attached). I bake it in cycles. If I choose ray distance setting = “1” those strange areas appears on the top side of the legs.



If I choose the ray distanse equal “0.1” areas disappears from top side of the legs but it appears under the knee of the character.


I can’t figure out why does it happends and how to fix it. Meshs is ok, there is no flip normals and so on. There is blend file whis high and low poly objects I used to bake normals attached.

You need a carefully edited baking cage for that to work, for more info google baking cage, it’s been discussed hundreds of times.

Here’s a cage that works:

Thanx a lot! I did not use cage setting at all, thats good to know. Thank you very much!
