I’ve been playing around with determining the right Maya Scale to Unity Scale and I discovered some things.
• A 10×10
Centimeter
plane exported from Maya is exactly the same size as a Unity Plane with a default scale of 1,1,1.
• A 10×10
Meter
plane exported from Maya is, as you’d expect, 100 times bigger than the default Unity Plane scale. So if you scale up the Unity Plane 100,1,100 it would be the same size as a 10m square Maya Plane.
• A 10×10
Millimeter
plane exported from Maya is 10 times smaller than the default Unity Plane scale of 1,1,1.
Looking at the grid in Unity iPhone, there are major units and minor units. When converting scale from Maya to Unity, you can think of:
• Major units as 1 Meter
• Minor units as 1 Centimeter.
Based on these findings, I no longer think that setting Maya to Millimeters (as I suggested in the Unity iPhone Touch Animation Tutorial) is the right choice.
Either Meters or Centimeters looks like the right way to go when creating objects in Maya. Deciding which one to work with is probably up to personal preference and different projects might end up working better at different scales.
