3D cast shadows disappear on random frames - Adobe After Effects 25.6

[ignacio28623194weum]

Hi! I have a scene where I did a camera track on some footage. Then I added a 3D object, a shadow catcher plane, and an environment light. Everything works fine as long as the footage layer stays visible. But when I turn off the visibility of the footage (I need the video to be transparent for another comp), the shadow starts randomly disappearing on different frames.

I’m using Advanced 3D. This also happens in other comps with other objects, sometimes instead of disappearing, the shadows get distorted or flip orientation. I don’t have any keyframes on the light or anything like that.

Any tips or workarounds would be super appreciated. Thanks!

HI there,

Thanks for writing in. Could you share your system specifications (CPU, GPU, RAM, OS version)? You can try clearing the media cache (Edit > Purge > All Memory & Disk Cache).

Let me know how it goes.

Thanks,
