Hey there @Gagan1403! Welcome to the community! Assets aren’t meant to be downgraded, so they can often cause issues trying to migrate them backwards. Usually it’s more recommended to export the assets out to a separate universal format and reimplement. > [@Backward Compatibility for Assets](https://forums.unrealengine.com/t/backward-compatibility-for-assets/156972): > > Backward Compatibility With regard to a workflow for getting Unreal editor assets FBX mesh, Textures and Materials into previous engine 4 versions, you must have the newer and older versions editors installed on your system.
