hi guys,
thank you for your suggestions
now i changed some textures straightend the verticals and took a burn value of 0,1 but still in linear multiply, reinhard didn`t look too good at the moment. i still have to figure out how to improve the picture, but o think it`s a little bit better already. one disturbing thing now is the texture of the inner walls of the higher building.
will keep on working on it.
