The biggest bottleneck I'm finding now is the time spent waiting while assets convert. I'm not talking about the manual work of preparing and lookdeving the asset, but the automated process that PiSquare runs when you click "Convert into UE Asset."
In my experience, it takes 2.5 minutes to convert a standard character skeletal mesh and 1.5 minutes to convert a simple static mesh. If you have lots of assets to convert, obviously this becomes a big time cost. I wonder if a large part of that conversion time is the UE project loading and unloading in the background? Would it be possible to leave it running if you had many assets to convert? Sort of like an asset conversion server?
