Hey, Im trying to put together a business case for my employers to start using unreal but the biggest hurdle ive found is the fbx import times and the strain it puts on my machine. Autodesks stingray engine, whilst alot less capable, produces similar graphics quality straight out of the box (obviously Unreal is much more powerful once you start editing) but i tested the import with a 70MB fbx file straight from revit and stingray used 700mb of ram and it imported in about 2 minutes. unreal got to 26GB!!! and it takes an age. Literally about 20 minutes. Why is it that Unreal handles FBX files so badly yet a brand new fairly standard and a little bit crappy engine from autodesk can in a fairly streamlined way, handle them tremendously fast?
From An Archviz perspective it would be a dream not to have to break down your models into chunks to import into unreal but its probably a problem for more than just myself.
