Does anyone have any thoughts on how to fix this or where I can find 3D humans that are just as good as these that work with VW? As a side note to VW staff: you really need to get on board with V-ray and other third-party apps like these mesh figures. There is a smoothing angle option for import and I tried playing with this, but it didn't do anything. When rendered in Vectorworks Styles (Realistic Interior Fast or Final) the textures appear shiny and/or missing. When I first did this, I was really happy because as I checked them in Shaded mode they all looked just as good as they did in 3DS or FormZ. This format conserves the texture maps and even loads them into Vectorworks as textures. I can, however, open the native files in either 3DS or FormZ (which I also use) and export them as. As with many such third-party products, these are not made native for Vectorworks.
I don't recall where they downloaded the 3D humans they use, but they are complex meshes with even more complex texture maps. My company includes designers who use FormZ and 3D Studio Max.
