No assets compatible with 4.17?

Im trying to import the animation starter pack and some infinity blade assets into my game, but none of them are compatible?

You can create the project with 4.16 and import the assets into the 4.16 version.

Then use Windows Explorer (or Finder if you are a Mac user) to copy the contents into another 4.17 project

Have you tested that they work in 4.17?
