Flamboyant, I've not used Newton collision at all, so unfortunately, I can't provide a direct solution. If Newton allows for trimesh data to be used, i.e. take a standard DBP object ID and pass it into Newton as a standard object, you may want to use the CSM GROUP TO OBJECT function. Basically since your CSM map files consist of at least ONE group, you could call this function to obtain the object identities that make up your map. Once you've obtained the object IDs, pass these into Newton for generating the collision map.
I can't really explain this in any more detail since I don't use Newton, but I'll try to help as much as I can.
