I'm not familiar with how the material properties for the scenery are handled. There's indication in the materials.xml file that material colors are not used unless the textures are turned off. In any case the diffuse color I would think ought to be full white for anything textured. The ambient value is the percentage of ambient light that is reflected by a material (added on to diffuse). You can try _decreasing_ the ambient value in the material properties which should increase the shading contrast in the scenery without changing the ambient light value. If everything is working correctly in the rendering code, using a material ambience of 0.500 and a light ambience of 0.080 should give you the same result as a light ambience of 0.200 and material ambience of 0.200 (both multiply out to 0.04). In any case the default material property values in ac3d are not the same as the light properties. I'm not sure what he's using for the lights. AFAIK they can't be adjusted.
