Sticking A Projection Onto Animated Geometry In Nuke

How to project an image or paint a texture onto animated geometry, and have it stick to it.

Projection Method

If you want to project an image/texture onto animated geometry you can use the setup below. It projects the texture onto the geometry on a reference frame and outputs the projection as a UV texture map. The result is then applied back to the animated geometry.

The setup for the Projection Method. Keep in mind that your image does take a filter hit when rendered out as a UV texture map, so make sure to use a high enough resolution in your Reformat, and sharpen as necessary.

UV Paint Method

You can also paint directly on the UV texture map and apply the result as a texture to your animated geometry using the setup below.
