Sheen Maps

Sheen Color Map – defines the color of the sheen effect per pixel. Use a full-color texture to tint the highlights: like purples for silk or gold for fine fabric. Black (0) disables the effect locally.
Clearcoat Roughness Map – controls how smooth or rough the clearcoat layer is on a per-pixel basis. Its influence can be controller by the Clearcoat Roughness slider in MaterialSettings
Sheen Roughness Map – controls how diffused the sheen highlight is across the surface. White (1) makes the sheen matte and soft; black (0) gives it a sharper edge-glint.
Wrap S / Wrap T – define what happens when UVs go beyond 0-1 in the horizontal (S) or vertical (T) direction. Repeat tiles the image, Clamp stretches the edge pixels, and Mirrored tiles while flipping every other tile for a checker-seam look.
Flip Y – inverts the texture vertically; turn it on if your image appears upside-down due to differing UV origins.
Anisotropy – boosts texture sharpness at glancing angles; higher numbers keep details crisp on surfaces seen from the side.
Rotation – spins the entire UV space (in radians), letting you align stripes or grain precisely.
offset X / offset Y – shift the starting point of the texture; handy for sliding patterns or matching seams.
repeat X / repeat Y – control how many times the image tiles across each axis: use integers for even tiling or fractions for stretch effects.
center X / center Y – set the pivot for rotation and scaling; (0.5, 0.5) rotates around the texture’s true center, while (0, 0) pivots around the lower-left corner.
