The typical limitation of UE. They, at least, should allow the engine to ‘try’ to open it; things without internal changes should work really fine! Only those with new functionalities could not work, but that should be OUR problem, not being automatically fully locked, without the freedom to make the try… I already suggested it, but it seems nobody cares.
Yeah since they changed the physics engine i don’t think you can revert back versions only convert in place to a higher version, if converting in place certain blueprints may not function like the previous version so you may have to fix them in particular circumstances, others will convert fine simple props or environments convert fine but anything with physics like motion to cars or other animations may break during conversion, best thing you can do is always keep an old version separate as backup in case you need to revert, but no you can’t start a project in 5 then go backwards in versions with the same project.
Sucks that you can’t downgrade. I mean, makes sense with Nanite not being supported… but considering the fact that V-Ray only works in 4.27 it just… sucks. Does anyone know of a vray work around for 5.1?
