匹配maya与unity3d二者的尺寸比例关系

           原标题：Finding The Right maya to Unity Scale
         

           非常有用的经验之谈，想必我们在向unity3d导入模型或场景文件时，不时会遇到比较不对或场景错乱的问题，主要原因还是因为三维程序和unity3d的坐标系及尺寸比例关系不尽相同，下面这是总结了maya与unity3d的尺寸比例的匹配问题。
         

           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.
