CommandBuffer: temporary render texture not found while executing (Copy source)

Unity Engine

I’ve been struggling to get a camera to render on a texture, and then display it on a composition layer Quad, only on an Android (Meta Quest) build. It renders once and then stops. I have this warning in both the editor and in a dev build:

CommandBuffer: temporary render texture not found while executing (Copy source)
CommandBuffer: temporary render texture not found while executing (Copy destination)

I have no solution, just seems broken to me. If anyone knows what can be the cause of this failure, that would be great. So far I’ve tried many things:

  • With and without MSAA
  • With and without Depth-related options
  • Different color format on the RT
  • Updating Unity
  • Render on the same renderer or with two different ones

At some point it worked, but then I just synched with my teammates on version control, and it broke again, for really no apparent reason (I kept all my changes intact, and their data was mostly art-related). It seems very fragile and I just don’t get it.

Hi @alexandre-fiset,

Thank you for your detailed report and for your patience while we looked into this issue. I sincerely apologize for the issues you have been facing as well as the delay in our response. I’m new to handling this repository and I’m working to better understand all the lingering issues to ensure we address your concerns as thoroughly as possible.

The behavior you’re describing (layers rendering once then freezing, along with the CommandBuffer warnings) is definitely not the intended experience, and I appreciate you taking the time to document your troubleshooting steps. To help us investigate further, could you share a minimal repro project that demonstrates the issue? This would allow us to:

  1. Isolate the problem (e.g., texture copies, URP settings, or plugin interactions).
  2. Verify fixes more efficiently.

We’re committed to improving the stability of Composition Layers, especially for Meta Quest builds, and your feedback is invaluable in that effort. Thank you for using our product and for bringing these issues to our attention it will help us make the tool better for everyone.

Please let me know if you’d like any guidance while preparing the repro project. I will make it a priority to look into this issue once we can repo the issue.

Thanks again,
Lianne
