In the Flame 2018.2 Update videos, we introduced an enhanced UV tracking and shading functionality that you could use with the Action projectors.
This helps with various texture projection tasks as well as motion graphics type work.
In the Flame 2018.3, Update the Projector controls underwent a bit of an upgrade in order to accommodate the additional motion vector enhancements as well as support for multiple UV references.
So this video will show you how to take the projected texture on a 3D model and track the UVs using the upgraded interface.
The rest of the original exercise is still valid in the Flame 2018.2 video covering projectors, UV tracking and shading.
