Track Matte Won't Work with 3D Layers in Ray-Trace

Hi all,

Having an issue here.

So, I have some font and a line that I want to move out from behind a logo that has transparency and there is moving footage behind it, but I cannot just duplicate the footage since it changes for each episode and they might change speed of the animation in Premiere, etc. When everything was in 2D, it worked fine. I used Track Matte; no problems. However, now that I am in Ray-Trace and everything is in 3D, the track matte no longer works and is also grated out in my options.

How could I get this to work?

Thanks!

Time for Plan B. Ray tracing and track mattes don't work.

Depending on your AE version you may have C4D Lite bundled to do extrusions. Adobe dropped all development on Ray Tracing.

I actually found a work around after I posted this; just have to precompose the 3D and lighting in Ray-trace first and then track matte the pre-comp in classical afterwards.

Yeah, that's the way. I put all my Ray Traced stuff in it's own precomp to avoid working in Ray Traced comps. Really limiting, but the advantages of using the Ray Trace engine are pretty sweet at the moment. Pretty soon tho, nobody will be using it when the C4D integration with shape layers comes out. Imagine using bend deformers with extrusion and rendering faster than the Ray Trace engine?
