Here is my expierence, or to better be called, my first shy tries to this collossus shader
-I first opened Warehouse Model Pack, and selected the Single Locker Asset, wich i had shaded for a previous map, i took the d2 texture, and putted one more layer Blue like normal mapping, i made it transparent, and the texture below too, i putted this same tex as <tex>_I and <tex>_N in dds format, when i tested they looked weirdly, as i passed the camera played the wrong with me

it lost detail as i passed trough the room i had created
-as my second attempt, i selected Single Locker again, and this time, i opened it up in gimp and went to Normal Map Filter, i putted a slight normal map with a blur, and now i tested, this time it came with a really cool effect, but not to betold Realistic
as the asset has a sheet of paper and a lock to one of the lockers doors
I hope the next one is more easy, as i watched 3 times the Video, and did the exactly, maybe, for details in the tex, is not recommended this shader?
