+
+ 1) create a new scene wrapper
+ 2) populate an array of of meshHelpers for each mesh in the original scene
+ 3) (eventually) create an animator instance
+ 4) scale the asset (needed?)
+ 5) create the asset data (GL resources, textures etc)
+    5a) for each mesh create a material instance
+    5b) create a static vertex buffer
+    5c) create index buffer
+    5d) populate the index buffer
+    5e) (eventually) gather weights
