hi all
i would like to say something important here in this particular
subject...
rendering pass (color, reflections, specular, occlusion,...etc)
is more professional than making one frame inside any 3d package.

any movie if you see it's making you will understand the importance
of the passes..
with it i can control any thing in post.

i want to mention something i (think) that most of you dont know
does anyone know that i can change lighting in post..??
does anyone hear about this..??

there is a shader called normal map shader that make the faces
colored with its direction in world
faces which looks (Y) will be green
faces which looks (X) will be red
faces which looks (Z) will be blue


so in post (composting like afterEffects) do color correction but
dont change anything
then after this color correction i make (hue/saturation) and make
the saturation=0
then the image turns to black and white
then select the color correction and decrease the red.
what you should see... (a black and white image) but the parts
that was red before (hue/saturation) gone to dark
means that light direction changed.
and do the same with blue... the parts that were blue gone blackand sooo on

so you can control the direction of the light by colors.

and much much more in composting....
not just color correction .. the image means more than this

so with passes i can control reflection for example i can
change its color, i can give it a ramp opacity, i can mask it
and do some tricks...

to understande what i am saying ...
see this studio ....!!!! my dream ..!!!! to work there some day
...?? who knows.....!!!
