U guys been awesome. Never experienced such good support.
Here is the final procedure:
-
Download: Free Enhanced NormalRGBMat
This ZB Material has the best colour profile for rendering Normal Maps in the real-time renderer, and it gives very lush bumps. -
(I dont know how to thx everybody.) Here is a little tutorial how to flip the green channel in ZB.
-Setup 3d scene for testing.
-Load the downloaded Mat (Free Enhanced NormalRGBMat).
- Create MatCapTexture.
-Create new document to clear the canvas and set the size to for example 1024x1024.
-Load current Texture as Image Plane. This is the only way to make MatCap texture ready for editing.
-Capture the canvas to Texture.
-Flip the Texture Sample vertically.
-Set the new flipped texture to Material as a new colour profile.
-Now u should have full functioning Material for rendering anything in ZB out to UE4.
-Turn off the shadows.
-Export the Canvas as a texture.
-
Take the texture to NVIDIA plugin and normalize it:

-
Should look pretty good in UE4 with compression. In this case there is some little artifacts there, but it could be because of ZB rendering and not enough polygons in the sphere.

And here is how it looks in the action:
