Question about lightmap materials

Hi all,
I'm currently attempting to implement some custom renderable objects. I want to be able to export some scenes from 3DS Max and Maya with baked lighting/shadows.
What's a good way to handle the rendering of lightmaps with the TGEA material system?
I noticed that you can specify multiple textures in the materials i.e. baseTex[0] and baseTex[1], but if I set baseTex[0] to my texture map and baseTex[1] to my light map, all I get is the lightmap rendered. I've tried playing with translucent and translucentBlendOp values for the second pass but it doesn't seem to make a difference. I just need a simple multiply of the texture sample by the lightmap sample.
Will I need to implement a custom material with my own shader for this, or is it something that can be accomplished with the default material system?
Thanks,
Gerald

Don't think it can be dun yet ...but the link below hes working on itwww.garagegames.com/blogs/105708/15776

I was just wondering if the texture blending could be done with the base material system, I didn't want to do it with DTS, as I'm creating my own specialized renderable objects. However, after looking at his demo project I see that he's using a custom material for his rendering, so I just went ahead and dived into making a custom material myself, which was fairly painless.
I guess I needed to learn how to use the custom materials eventually anyway.
