Some textures will use masks to apply things like makeup - rather than having a face map with no makeup, a face map with makeup 1, a facemap with makeup 2 and so on they will have one face map, a series of overlays with just the makeup and black-and-white images showing where the makeup should be applied. Those won't work in DS base, though they can be set up in the DS Advanced Shader Mixer 9and presets could be saved from there which would work in the free base version of DS). So that's one thing to watch for - it can be useful to look at the file list in the readme to see if there are image texture files named something-mask or the like.
