I'm looking at a different outfit by AS with a similar shader arrangement and similar render settings and light conditions; I get the same issue.  Increasing the Raytrace bounces appears to remedy the image quality under IDL.  IMHO, the Material shaders are not correctly composed for an IDL environment.  My best recommendation is to remove the Fastscatter from the Alternate_Diffuse and reroute the Color-Math node connected to the Diffuse_Color to the Alternate_Diffuse.  Connect the Diffuse map to the Diffuse_Color connector and 0 the Diffuse_Value.  In my assessment, the Fastscatter node is not contributing anything useful to the math.

Well, let me tell you what I did. I did exactly what you explained here, and it was a 'No Go', still black as my gothic heart, but what I DID do that made it work was simply disconnect the Fastscatter node from the Alternate_Diffuse and connect the Image_map node of the real texture directly into the Diffuse_Color, but keeping it 1, not 0.

I have no Idea what that means in Shader Language, but at least is rendering.
