The shadow buffer full error appears when the buffer required to process/store the shadows is larger than the shadow pool.

In the file provided, the shadow pool size is 0, so the error message is expected because the buffer required is bigger than 0.
What's unexpected is that you've set the shadow pool size to 0, which isn't a option in the UI.

If you could share the steps to reproduce set the shadow pool size to 0, that would be helpful.

Unfortunately the file comes from a very complex scene with many levels of libraries in use, and I removed everything and just add minimal objects to expect a shadow. Other files with complex scenes of mine work just fine.
Appending the scenes in a new file is not an option since library dependencies will be lost.
Linking the scenes in a new file (and making local all the stuff from the original file) fixes the problem. But this work around requires a lot of work.

Without clear instructions on how you managed to set the shadow pool to zero, we can't properly investigate this issue.

In the meantime, to make your current scene work you can increase the shadow pool size (see the attached image the shows where the shadow pool size option is)

Thank you for the workaround.

Without clear instructions on how to set the shadow pool to a size of 0, and the fix being as simple as changing a value in the UI (or getting a simple Python script to do it for you), I will close this report.

If you do know the steps to set the shadow pool size to 0/an invalid value, please let us know.
