No PCG after package project

In my project, PCG generated contents disappeared when I packaged project. why this problem happened?

Hey there @Anonymous_c79436488919bada0758aadc60ce0d76! Welcome back to the community! Were there any packaging errors in the build log? Are the colliders for the PCG elements still there? (As that could mean the issue is visual and not purely packaging).

No problem in building, I want to save PCG generated content in editor, not runtime generate.

Apologies! Just to make sure I understand, you’d like to save your PCG that you setup in the scene, as an asset in editor. Is that correct?

If so, I’m uncertain the proper method for 5.4 and below, as it was intended in version 5.5 to be able to quickly save them to PCG Data assets as referenced here:

However the data assets were previously implemented so it may be possible to use them, though I could find no documentation on it. However, if it’s intended to be placed in the same location, you could save the seed itself instead, but that could change wildly if anything in the environment were to change.
