heyas; not in poser. you can tell lights not to cast shadows (at all), but you can't set materials' abilities to cast or recieve shadows. however, if you're working with mist/fog, you could try messing with the ambient colour. instead of having the ambient be black, make it the colour you want your fog to be. the ambient colour defines the colour of the material in shadow, so this may eliminate shadow visibility in your fog. so, okay, maybe it can be done in poser. :) i'm not sure, though, so try it out and report back!
