11. The system of claim 10 , wherein the one or more processing units are further configured to render the polygons of the lower depth mesh where the mask is applied.
12. The system of claim 9 , wherein the one or more processing units are further configured to set values for each shared polygon indicating whether each shared polygon is fully occluded or partially occluded.
13. The system of claim 9 , wherein a first mesh of the plurality of meshes is a mesh of a base 3D asset and a second mesh of the plurality of meshes is a mesh of a following 3D asset.
14. The system of claim 13 , wherein the base 3D asset is a bipedal humanoid character, and the following 3D asset is an article of clothing.
15. The system of claim 9 , wherein a first mesh of the plurality of meshes is a mesh of a following 3D asset that is associated with a base 3D asset and a second mesh of the plurality of meshes is a mesh of another following 3D asset of the base 3D asset.
16. A method of rendering electronic 3D content, the method comprising:
