heres two different settings i found from google but my question is what are your settings and why do you use those settings ?
udk to maya scale = 1:1 ratio
16uu = 1 foot
setting up the grid in maya
Grid Lines Every: 512
"This will give you every grid unit in Maya = 16uu.
How did we figure that out? We took
Grid Lines Every: 512 divide by Subdivisions: 32 = 16.
512/32=16" it means each grid square equals one foot
1 Unreal Unit (UU) = 1 Centimeter (CM)
So as a working grid in Maya, you should set your grid accordingly:
Length and Width: 1024.00 units
Grid Lines every: 16.00 units
This will give you a grid in Maya that represents using a 16uu scale in Unreal.
this is what i found but i dont think this is right. one says each unit is 1 foot and the other 1 centimeter
