Adds a normalized STMap layer to the incoming image for UV-based warps and coordinate-driven workflows in Nuke.
Channel STMap builds a standard STMap on the incoming image. Red and green hold normalized pixel coordinates: (x + 0.5) / width and (y + 0.5) / height, written into an stmap layer and copied onto the source so RGB and other channels pass through unchanged.
Use it when you need a clean UV reference matched to the current resolution—STMap warps, custom displacements, or any setup that samples by normalized screen position.
The gizmo is a fixed utility with no exposed controls. Resolution follows the input; the map is full-frame and ready to pipe into STMap, IDistort, or similar nodes.
