STMapper
Distort layers with ST maps, plug in UV passes from your 3D renders, and create blank ST maps to bake down your transforms and distortions.
If you’ve ever round-tripped through Nuke just to apply lens distortion, wrestled to use a UV pass from a 3D render, or given up on baking down a stack of transforms into something reusable, STMapper is for you. It brings the industry-standard ST map workflow natively to After Effects, with a streamlined and easy-to-use workflow.
