Tiling: Why is there a differenz between "Rotation Angle" and "Detail Normal Rotation Angle"
Completed
Hello,
I wonder, why the detail normals are (maybe if I understand this correctly) not following the same Rotation Angle like the Tiling.
However, when I change the rotation angle for Detail Normal Angle, nothing changes.
Many thanks for explanation

Hello Quixx,
Thanks for reaching out. If you open the Master Material for either MS_DefaultMaterial or MS_DefaultMaterial_Displacement you'll notice that there are two Material Functions on the far left side of the material graph, "MF_Tiling" and "MF_DetailNormalTiling." This allows for each parameter (Normal and Detail Normal) to be controlled and rotated individually within the Material Instance.
You'll notice that the DetailNormalTiling material function is plugged into a Detail Normal texture input, however, this texture input is a blank Normal, therefore, rotating the Detail Normal will have no effect on the overall material unless the detail normal parameter is enabled and a normal map is selected within the Material Instance first.

Thanks for reply. So as I understand now, there are different inputs for two kinds of normals.
Maybe "detail normals" is intended to use for a micro structure and "normals" for the main shape?
This would explain it to me. The confusion is, that I never had heard about "detail normals" before and I guess that this is just a second input, to overlay the basic normals.
Is that right?
Thanks!

You've got it! That is correct. To further explain the usage of detail normals feel free to check out this video that I thought would be of assistance to you!
