I know this has been asked to death (at least on UDK), but unfortunately, there is also many different answers.
Before getting to UE4, let get back to UDK.
I have heard that the default character is 96 unit high, as well as 1UU=1cm, to 1UU=2cm.
Yet, when I load UDK (2013 July version), with one of the main character, he is closer to 128 unit tall. Again I load my real world scale Maya character of about 170cm tall, she looks like a giant in UDK. I discover that I can get her to my eye level by scaling of about 0,75.
Also, I have heard that Skyrim use character of 128 height, for main character of about 6ft, 128/183=0.7
So in the end, I used scale of 1cm=0.7uu, or 1uu=1.43cm. It works fine for assert created in UDK I guess.
Like everyone else, I would like to make the jump to UE4,
But now, I am back to the headache again. I haven’t got UE4 yet (My PC is a bit under the spec), but soon (after I upgrade my rig).
I do not want to create my asserts & then have to waste time to rescale & rematch grid points (especially hard for the high poly normal map models). The latter point about make nice perfect UU size model is critical in modular design.
So do anyone know the default unit conversion in UE4?
