OK. Here's my latest attempt. I'm sure it can be improved, but I think we're on the right track now.
Here's the revised DBPro code snippet:
`Set Up Display

`Brightness

I've made so many changes I've lost sight of the critical ones. The main change, I think, is that the code now deals with just one object (.x file). When you run the code the area is initially very dark - so it's hard to tell when it's actually loaded and ready to go. If that's a problem just increase the ambient value in the DBPro code - that's something I added to the code and the shader.
The downside is that I'm sure something has been lost in the lighting - perhaps that's the lightmapping you were referring to? Anyway, now I've sorted out the main problem, we can move on.
I'm sure we can fix the lightmapping - I'd forgotten it was there.
Let me know what you think and if anything is missing, i.e. textures, lightmaps, etc.
In the meantime I'll see if I can find the lightmap you referred to.
Edit: OK, I've found the lightmaps. I completely missed the point of the second object. Sorry. Is there any reason why you can't apply the lightmap to the original object - i.e. have the textures and lightmaps in one place? I can then adjust the shader to read the appropriate texture stage UV coords. All I need to know is the texture stage for the base texture and the stage for the light map - and if you don't know, I can probably work it out (did something similar for Overdroid the other day).
