Is there any way to import marketplace items with the 4.8 editor?

Can’t you just put them in the content folder of your project? You’ll have to fix dependencies manually i’m afraid so it is more like a workaround.

The Unreal Editor for Linux does not include a button for the marketplace. I was able to download some marketplace items using someone else’s computer, but everything is in a .uasset format that won’t import into the editor. Is there any way I can use marketplace items, or do I have to wait an undetermined amount of time until the feature is available for the Linux editor?

That worked, for the most part. Some items still don’t appear, so I’ll have to try to fix those.
