Transparency map in Poser = opacity strength map in DS. There are two potential issues: - because Poser sets a maximum transparency and DS a maximum opacity, if your range isn't 0-100 the results will differ or be unmatchable using plain settings (if, for example, you have set the TransMax in Poser to 50 and are applied a map the surface will be between 50% transparent and opaque; but in DS, if the map is used directly with the default values the surface will vary between fully transparent and fully opaque, or if the numeric value is set to 50% it will be between fully transparent and half-opaque, neither of which is the goal). - again, because Poser and DS are measuring from the opposite end if you have a black map applied to a material in Poser that has transmax set to 0 the material will be opaque, which may happen when people set all the materials to a common starting configuration and then customise, but in DS that will be seen as a surface with a maximum opacity of 100%, a minimum opacity of 0% and a map setting the opacity to 0 throughout -the oppoiste of the Poser look. The second issue can be avoided simply by removing the transparency map from any material that doesn't need it, but the first issue is trickier - I would use the layered image editor to add a semi-opaque white overlay to the transmap, say at 50% fro the example above, so that the map went from 50% grey and white instead of black to white and therefore gave the result in DS that the bare map gave in Poser but it would be hard for you to talk the user through doing that (though it isn't actually hard).
