First of all,I’m sorry for my bad English,I am Japanese I can’t speak so well.
My question is if I continue making scene in unreal engine using default blender scale unit is there any problem might be happen in my future development.
If there are I wanna know what is going to be wrong for me.
After all ,in terms of static mesh,answer is no.
But in case of mesh using bone there has possibility but you cant know until you export the animation and seeing the result inside the engine.
