Body Models. Removing verts?

[Canderis]

I know its not possible (or maybe possible but not easy) for heads but can you do it to body models w/o many problems? I know you have to do weighting. What is that exactly?

[DarthParametric]

Weighting defines how a mesh is affected by the bones (which are driven by the animations). The reason you can't delete or add vertices is because it screws up the weighting. Plus there are export issues as well from what I gather (even if you reweighted the mesh).
