Need help with Wavefront obj Importer

I’m using Blender 2.49b and when I import a particular obj file, it loads into Blender without any errors, but it always appears black in the 3D View. It seems to render okay with its texture, but when I export it out to pureLIGHT in dae format, it is drawn as a black object in pureLIGHT. So I think I not importing it into Blender properly.

The file has an .obj and a .mtl with it and the following files in the same directory:


I can only see where the cactus4_color.tga is set. I can’t see how the others are used in Blender though.

Has anyone got any ideas, why an object would draw as black in the Blender 3D View?
