UE5.2.1 Packaging error:Unknown Cook Failure .Could I trouble you to help?Thanks.

[yanccee]

I am still in process in UE5 learning,and I just instaled the Visual Studio 2022.
However,when I was packaging it as the course of the study,it errored.
Could I trouble you to help?Thanks again.

This might have nothing to do with Cesium; you should carefully review the log files to look for other causes.

[Kevin Ring]

Yeah @yanccee from the log it looks like a problem with some materials in a plugin called FXVarietyPack, nothing obvious to do with Cesium. So I'm going to close this issue, but if you do think it's Cesium related, please start a thread on the community forum instead of making a GitHub issue, and include as much detail as you can, particularly around what makes you think it's Cesium-related.
