Hi, recording team; please ask new questions in a new thread. Thank you.
Mixing threads will make it harder to search or read.
For now, leave it here.
Drag the lib4d file to the Asset Browser.
An alert will come; click OK.
When double-click on the icon of the new file in the Asset Browser, another alert will come up: Do you want to convert it? Yes.
Then, look for the Convert Folder in the Asset Browser.
It should work if the file in the lib4d file is compatible and has all the needed parts.
All the best
