Player Models with Multiple Source Textures

I picked up some Q2/Q3 player models from PolyCount, imported them into MilkShape, applied the textures that came with the models, and exported tham as dts. Some of them worked great, others did not. For those that did not, in console.log, I noticed the "You do not have the correct version of..." error that comes up when a model cannot find its texture. The player model textures are in the same directory with the models as they should be (and in one of the correct formats, png). The only difference I can find so far between those that have worked and those that have not is that the ones that don't work have multiple texture files applied to the model (i.e. one file for the head and one file for the body) as opposed to a single file for the entire model. Has anyone else ever encountered this? Is there a less time-consuming work-around than UV mapping the model and reapplying the textures to the UV map so that it is a single file?
