Vladimir: too busy at this time to check those textures how they look in the engine.. im just trying out your great FilterForge.. i have plans on using those textures in my doom3 project. At that time ill probably realise all the things i could have done better. But normal height could be adjusted by Surface Height so its easy to correct it to desired height. I was looking for a good result in FilterForges render..
Mike: hehe.. not intentionaly.. i checked the texture you are talking about.. and it really looks like i stole the look

but mine started as an atempt to do distroyed road texture and ended like a wall

similarity is coincidental
James: Thanx
