ReadonlybaseShared RGBA color atlas; alpha supplies coverage for color, normal and roughness together.
Optional ReadonlybaseEncoding of sampled RGB. Use linear for hardware-sRGB textures. Defaults to srgb.
Optional ReadonlynormalOptional tangent-space normal atlas, with the same rectangles as baseColorAtlas.
ReadonlyprojectorsOne to eight projectors. Membership is copied; projector data can change through update().
Optional ReadonlyreceiverMaterial receiver mask intersected with each projector's layer. Defaults to all bits.
Optional ReadonlyroughnessOptional linear roughness atlas, sampled from red; same rectangles as baseColorAtlas.
Bounded atlas and projector membership for one opaque PBR receiver material.
