Problem with Akae textures and Luxus

LandsoftheEast

Akae is one of my favorite characters, and I would really like to be able to use her with Luxus/ Luxrender. However, whenever I try to do so, her skin comes out very splotchy. This does not seem to be a problem with 3DDelight, as I have rendered her many times without trouble.

Also, I have used a wide variety of light set ups in Luxus/Luxrender , and all have given me the same result.

You can see in the first image the splotches are visible in the preview screen.

In the second image, rendered with 3Delight, they are gone and this is very nice looking.

In the third, Luxrender via Luxus- the skin is very splotchy.

A few notes:
I first thought it was a bump map problem, so I dialed that way down (0.003) in Luxus- no difference.
The attached luxrender image only went to 33 s/p, but I have let it go to 2,000 s/p and up without the splotches disappearing.
Akae comes with special DS materials, I have used those and the default with no luck.
A friend who also has Akae, but uses Reality and Poser was able to render her splotch-free.

Any ideas what might be causing this? Any help or advice is much a appreciated.
