Spherical mapping create UVs using a projection that is based on a spherical shape wrapped around the mesh. This projection is best for shapes which can be completely enclosed and visible within a sphere, without projecting or hollow parts. 
	 
To create UVs using a spherical mapping technique
- Select the faces you want to project UVs onto. 
		
- Select 
		  , or in the 
		  UV Editor's 
		  UV Toolkit go to 
		  . 
		
- Use the manipulator to change the position and size of the projection shape. 
		
- Use the 
		  UV Editor to view and edit the resulting UVs. 
		  
 
		  Note:  Projection mapping only works properly on a single object at a time. If you need to apply a projection to multiple polygonal objects in a single step, combine the objects into one, apply the projection, and then separate the parts. Otherwise, perform a projection on each object separately.
