Todd, this is welcoming news for After Effects users. A very significant step forward. Thanks for sharing this advanced news with the community here.

I know none of this is “official” yet, but any speculation on whether this update will also apply to a future AE CS 6 update?

Thanks again for this update!!

That “one feature” discussed in the “Important Note” is actually quite significant.

One of the most significant features released in After Effects CS6 was the Ray-Traced 3D renderer. And that is what the GPU accelerates with CUDA. Without CUDA acceleration, After Effects CS6’s Ray-Traced 3D renderer’s performance is nearly crippled, relying entirely on the CPU.

For reference of GPU vs. CPU ray-tracing performance, view the Radeon HD 5870’s benchmark (i.e. a non-CUDA, CPU Ray-Traced 3D benchmark) under the After Effects CS6 benchmark results at Bare Feats:

The CPU-based render is nearly 1100% slower than the slowest CUDA card tested and the render failed to complete!!

Moreover, the subject of this thread is related to the Ray-Traced 3D renderer, which is supported by numerous NVIDIA GPUs, including the GTX 780 which was very recently released (see link below).

It is extremely aggravating to see the GTX 780 “unofficially” supported in After Effects, but not the GTX Titan which shares the same GK110 GPU and has been retailing for a significantly longer period.

Also, I can appreciate that the testing for this acceleration is rigorous; perhaps there is a compromise where After Effects can “unofficially” support any CUDA card similarly to Premiere Pro CC.

“Also, if you own a GPU that we haven’t officially tested, but which meets the minimum requirement of having 1GB of VRAM and appropriate drivers installed, you will be able to enable that GPU in Playback Settings. An alert warns you that your configuration isn’t officially certified, but you’ll still be able to turn it on to use it. All this means that more people than ever will be able to enjoy full, GPU-enhanced Mercury Playback Engine performance.”

Raytracing support in AE for the GTX 780 and not the GTX Titan? Whaaat?

The GTX 780 and GTX Titan are both GK110! Adobe, please fix this!

[Zeno Costa]

No disrespect Todd, but limiting GPU support to only “user requests” is an inane policy, especially considering how much of the current Creative Suite/CC production software is dependent upon GPU acceleration.

I expect much more from a company like Adobe.

Gave up trying to find solutions. Found the best approximation was to render a flat lambert shaded scene with default lighting. I figure, RSMB will have the easist time working with this “motion pass,” rather than my RGB/beauty passes . . .

Ahhh, that would make sense . . .

Any other suggestions for producing motion vectors out of Maya OSX running mactel?

Downloaded and installed the osx .so file, but get the following error:

// Warning: (Mayatomr.Custom) : /Applications/Autodesk/maya8.5/Maya.app/Contents/mentalray/include/lm2DMV_v2.mi: couldn’t find shader library //

Any chance of posting exactly what all of the contents of the maya.rayrc file should read, top to bottom? I think I might have something out of order . . .
