Quote - Well I started to play with Reality last night, I say play because I have yet to read the manual past the installation instructions.  The first render I tried had V4 in the scene and while the clothe textures were exported correctly the skin tone appears to be greyscale.

Take a look at the original Poser shaders. Some of the advanced shaders (particularly ones based on Bagginsbill's work) don't use the diffuse input. If the skin texture isn't plugged into diffuse, Reality won't find it.
