The big question about Unreal 4 Scale

Thanks. I tried to scale by 10 and the Unreal character was then too small in my environment. I created my own scale factor based on the height of the character in relation to objects which I know the dimensions of and it seems that scaling by 2.5 had the best result. So at present (until I fiddle a bit more or someone else has input) when drawing in SketchUp (in millimetres) one will have to scale up by 2.5. Therefore 1mm = 2.5uu which doesn’t seem to align with the previous comment that 1cm = 1uu.
