I need to render out a 3D image, but change out the texture content in After Effects. Time for a “ReMap UV” vs. “ft-UVPass” shootout:

ReMap UV and ft-UVPass essentially do the same thing, but for the premium price increase, ReMap UV also has some additional features that may be needed.

I was needing to control the television image on a 3D tv screen. This was super-annoying to do in Cinema 4D–and I never did figure out how to effectively get the audio working. Anyway, it wasn’t worth trying to do in C4D. Remapping the UVs in After Effects (which I was headed to for post anyway) was the way to go. Remapping allowed me to easily have a comp as my “screen source” with the bonus of making it easy for my client to dictate changes to the screen content.

Both products effectively re-map the UVs, but I ran into a problem. I was getting aliased edges on my tv-screen, when the anti-aliased UV color moved into a new object. That anti-aliasing was changing the color of the UV map on those edges, thereby designating different content. In short, it made chunky edges of the wrong color.  ReMap UV includes a couple parameters to help deal with this. One is an Edges Threshold which tries to identify and minimize these edges, and the other is MIP-mapping, which is related, but also helps control your overall image quality when it stretches away from the camera (just like you’d want to use in the 3D app with a texture map).

In short, if you need simple mapping, throw $30 at ft-UVPass on for making it possible. If you need fine-tuning control, get ReVisionFX: ReMap UV, which is around $150.
