Recently working on Unreal Engine for a project but want to convert the whole project to Unity. Is there any way?
There's no tool or automatic conversion process for this. You will need to make such a conversion almost entirely manually.
It's possible you will be able to find tools to bulk-convert any assets that are in one format to another, although there is a good chance Unity also supports whatever (source) asset format you're using in Unreal. Unity will not process
.uasset files directly; you will need the source
.fbx files, et cetera.
But all the code, anything in Blueprints or C++, will need to be rewritten in C# and
MonoBehavior and likely heavily adapted in the process to Unity's rather different mode of operation.
