Normalize your textures!
admin
I made a couple SBSAR procedural filters for normalizing textures, since I couldn't find reliable tools for this. Maybe they can help you!
Normal maps should always be normalized before final delivery, to make sure the vectors are mathematically correct for optimal shading. It's easy to edit textures in tools like Photoshop etc. but it's not easy to normalize them properly.
Sometimes the shader will normalize for you, but it's not always guaranteed to happen. When a map isn't normalized, and the shader doesn't do it, you could see bad lighting and aliasing.
Same with anisotropy textures.
I did a webinar about how to make Iridescence and Anisotropy using glTF, and shared a bit about normalizing textures, you can jump to 21:35 to hear about that.

Normalize a 3D vector:
- Substance_Normalize3D.zip
- This normalizes a 3D vector stored in the red and green and blue channels of a bitmap.
- Useful for normal mapping, flow maps, etc.
- More info here: https://github.com/KhronosGroup/glTF-Sample-Assets/blob/main/Models/ChronographWatch/README.md#materials
- Substance_NormalizeRG.zip
- Normalize a 2D vector stored in the red and green channels of a bitmap
- Useful for anisotropy textures, maybe other things too?

The 2D one though is a customization which bypasses the blue channel.
I just wanted SBSARs I could open in Substance Player, and to share with people who don't have Designer.
I normalise the red and green channels and set blue to 1.0 just to upset graphics programmers
