I'm trying to bake a high res Normal map into a low res one. The high res is a duplicate of the low res; I used Multiresolution modifier. I also sculpted my model, then applied the Multresmodifier and all other modifiers for all objects. I'm using a cage mesh, which is again a duplicate of the low poly. I used Alt + S to scale all faces on their normals, so they have the same poly count as the low res Normal map.
The thing is, this is not the first time I have ever baked normals, but I've never seen something like this (check the image). I've double checked everything: All objects have smooth shading, all faces in my low poly are selected, and the Texture node is active in low poly's material node editor. I'm sure there's a logical reason for this, I just can't find it.
The second image is of the cage I'm using.
