I am sure we all know sutch customers right haha! If we are honest, we are sometimes like them too hehe!
I wanna thank you for your tipps - i allready use the script and yes - it is really very helpful!
But my szene is really very complex. About 40 different Materials and a lot of many different textures, bump maps and about 20 lights! In this i have some Evermotion Arch models and many self drawn objects. The Textures are very complex and look pretty amazing. The converter did in max a FANTASTIC job. All materials were converted, all textures were applied correctly - just great. about 30 minutes work and the materials were done.
To make all these materials look the same in Standalone will take many, many hours of work. I am allready on it, to get my job done, but to make ONE material as perfekt as in the max version i need about an hour and this time is time, that a: i dont have at the moment and b: actually it would not be necessary to spend this time, if the max plugin was allready out.
I told this the customer and he is willing to pay this time, so everything is fine - but.....i don´t have too much time at the moment

Have a nice day all. Kind regards chris!
