Transmission maps are essential for faking depth and optical softness in transparent materials, helping you create tinted windows, translucent jelly, or frosted glass with fine localized control.

The Transmission Map in Canvas Studio controls how much light passes through a surface, pixel by pixel, simulating realistic translucency like glass, liquids, or resin. It works alongside the transmission slider in the MaterialSettings to determine which areas are fully transmissive and which stay opaque: white (1) pixels let all light pass through, black (0) block it entirely.
While it may seem similar to an Alpha Map, the two have very different purposes. An Alpha Map determines visibility, making parts of the surface fully or partially invisible. A Transmission Map, on the other hand, keeps the geometry fully visible but controls how see-through and light-reactive the material appears.
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.
