Bump Map

In Canvas Studio, a Bump Map fakes surface relief by using a single-channel height texture to perturb the fragment’s screen-space normal on the fly. This adds light-reactive ridges and dents without altering the mesh itself. Unlike a Normal Map, which stores full XYZ vectors pre-baked into RGB and yields sharper, direction-aware detail, a bump map derives its fake normals from the height differences of neighboring pixels: quicker and smaller in memory but softer in appearance.
