DS does not load Poser specular maps so that has to be done manually which unfortunetly means browsing into the runtime "texture" folder.

Some content creators have no logical or consistant folder naming convention so this can be very frustrating when trying to find the missing textures.

Also the "surface" settings between DS and Poser are different. So manual adjustment is often required to get the Poser textures to look good in a DS render.
