I am trying to rig models for an old game using Blender. There is a poly limit of 5000. One thing has has proven to be a bit of a problem is that some of the models I am trying to rig have the clothes as separate objects from the base model, leading to unnecessary faces in the sense that the "skin" is not visible as it is blocked out by the clothes.
What I am wondering is, do I have a better way of deleting these occluded faces other than manually selecting them by hand?
What I've tried so far:
Merging nearby vertices and then selecting interior faces and deleting them. This kind of works, but merging them leads to vertices placed in between where the skin was and where the clothes were. This deforms the clothes. Perhaps there is a way to pick the outer vertices as the point where the merged ones should be?
Using the boolean modifier. This kind of works? Some faces definitely do get deleted on the "difference" mode, but not all of them. And, worse, depending on the object selected, sometimes it'll delete the entire body (e.g., in this particular case, the hair just nukes the whole model - example: http://sis.sy/WhiteTimidBeta).
If you can't tell, I'm a total noob, but I have tried (and failed).
