How to publish complete projects for all Unreal Engine versions?

So, I am a new creator on Fab Marketplace and I create complete projects and publish them to the store, so far I’ve downloaded UE4.27 and UE5.6 and I though If i upload project files for these, then it’ll be available for all engine versions through 4.27 to 5.6 (so naive of me).

Now, my question being, “is there any shortcut to make a project available for all engine versions, i.e, 4.27, 5.0, 5.1.1, 5.2, 5.3, 5.4, 5.5, 5.6 if my project is blueprints only and doesn’t rely on any engine specific logic but the math nodes and logic nodes that are consistent throughout all the versions, coz every time I migrate my project I need to rebuild the lighting for the maps and I don’t want to download all the engines considering their sizes on disk.”

Hey @Frigon_Tech ! How are you?

As far as I know, there’s no official shortcut to make your Blueprint-only project automatically available for all engine versions. If you really want to let the people know the project is available for all versions, you will need to upload each version individually.

But you can also upload only the project for the oldest compatible version and put something like “This project was made in UEX.XX and can be upgraded manually to newer versions (5.x) using Unreal Engine’s conversion feature.”, as it is created only with blueprints and not using any specific engine feature.

Hope this helps you!
