White walls, added a Normal Map.
Here is the file with the Normal Map:
- recalculate normals
- invert GREEN channel
- image is set as NON-COLOR
- the object is FLAT SHADING
These are chunks from the viewport in Cycles:
This is in Eevee viewport:
And this is a render:
And this is a render with the RED channel inverted:
And this is the viewport in Cycles without NM:
And this is the face orientation:
I activated backface culling, so there's no way any of the faces shown are backflipped.
Aaaand... this is the shader:
Nothing fancy really- I really don't know where else to bang my head now.
I don't seem to be able to use Normal Maps in Blender, though I perfectly know how they work, and worked with them for many years, I always meet some kind of problem in Blender.
What is the secret?
Edit: under suggestion, tried to plug some vector nodes in the shader:
