Adds a normalized UV STMap layer to the incoming image for warping and texture-mapping workflows in Nuke.
Channel STMap writes a standard STMap into the stmap layer on the incoming image. Red holds normalized X as (x + 0.5) / width; green holds normalized Y as (y + 0.5) / height, matching common UV center sampling.
Use it when a downstream STMap, IDistort, or similar warp needs explicit UV channels on the plate or pass you already have in the tree. The original image is preserved; only the stmap layer is added via Copy.
There are no exposed controls. Drop it on a stream whenever you need a full-frame identity STMap bound to that clip’s resolution.
