I’m currently working on an overhaul scaling to the level to match with Unity Design Standards!
This should help tons with building and importing into unity.
There is a folder in Drop Box that everyone should grab. It is Called Maya To Unity Size Ratio.
In it you will find a Maya Scene File that Contains some helpful references. A Max Model at roughly 4 ft high, cubes at 1ft size and cubes at 1 meter size.
There is also a readme file in the folder that explains a bit more. I’ll copy that in here for reference as well!
Both Maya and Unity share the same standard Unit Size.
1 Maya Unit = 1 Unity Unit
Import any Maya Models to Unity at a scale of 1
Maya grid should be set at default settings.
Keep in mind 1 Unity unit is = to 1 Meter
This applies to scale in Unity and physics in Unity.
So a standard 1 by 1 by 1 Cube in Maya also = to 1 Meter
In the Scene Provided is a roughly 4 ft tall Max Model, 4 1ft. cubes stacked to 4 ft high, a 1x1x1 Unity cube = to 1 Meter,
and a 1x1x1 Native Maya Cube = to 1 Meter.
Hope that Helps!
UPDATE: This only works if you are exporting your model as a Maya Binary!
FBX: If you are exporting from maya as an FBX, 1 Maya Unit = 1cm in Unity
Scale the models by 100 and you will be fine.
In this folder is also now a Level Reference .mb and .obj file with an updated to scale level.
Scale by 100 for fbx
