I’ve find this nice expression from Kevin Camp, but it’s designed to read the animation forward and backward.

t = thisComp.frameDuration*15;
if (time-inPoint <= t) time-inPoint;
else if (time >= outPoint-t) outPoint-time;
else t;

In my case I’d like almost the same, except the layer’s outpoint (minus the duration of the outgoing animation) plays forward.
Not sure I make myself clear :))

Yep, it should work, but the CUDA panel is empty.
The raytraced comps gives me a saturated memory error alert :

“After Effects error: Ray-Traced 3D: Out of paged mapped memory for Ray tracer. Your project may exceed GPU limits. Try closing other applications. Try updating the CUDA driver. ( 5070 :: 2 )”

That’s why i wanted to understand and fix the problem. I also tried to add my graphic card in the “raytracer_supported_cards.txt” but it has no effect. This trick is working on an iMac 27″ with a GeForce GTX 780M (i have tested today), and allows to select the GPU in the drop-down menu.

The last one, as i said. CUDA 8.0.46

I already did, all drivers for NVIDIA, CUDA, updates for OSX have been installed.

As shown on the screen capture, After Effects (latest version) recognize the graphic card.

Hello Dave, thank you I know about that already.
As I said if i had choice, i would prefer to work with C4D.
But the project I’m working on is not mine and I have to update many elements inside this project. It has been made using raytrace 3D and I have no other choice.
The problem is not raytracing, but why After Effects recognize my graphic card and still saying it’s not compatible.

Dan, thank you very much for your quick reply ! This is exactly the result i expected.
