I like what u are doing here LDR. Nice use of that crashed freighter. Is it too clean though? I would think maybe there would be more damage. Second, lighting. Too bright. You could try 2 different tactics. First, dim the lightmaps for each model, make them a tad darker...or..maybe play with the colors in .are file, the sundiffuselight and I forget the other.
Interesdting idea though. Good luck!
