Good News ! I had contact with pesmontis himself. He gave me his program lightsong and some extra documentation. I testet the program with an model but it gave me a "no DE FA" error. According to pesmontis , this is a material problem ... He don't want to give me the source code , but maybe someone can reverse engineere the code ;D (it's a VB6 program) or Make a new program with his documentation He gave me also some spellforce 2 .drs files , so we can check their file structure with our battlefroge .drs files. If someone needs more information from pesmontis , I can write to him. Here's the link https://mega.nz/#F!kltllJAB!2RMk13XRxV1DRm3KJrbfXQ
