Objects showing through other objects in the BGE? I am having trouble with a rig I imported from MakeHuman. When I run the Embedded Player or the Standalone Player my character's facial features come through the mesh. 

They are positioned properly, but for some reason they seem to get priority over the outer mesh and are displayed through the outer skin.

Here is a picture to illustrate my conundrum:
The simpliest way (and only one known to me) is to go to "user prefernces-editing" and in "Duplicate data" uncheck the "Metaball". Then duplicate problematic meshes. Duplicates shoudn't have these problems.
