Hi guys.
I have a situation which I believe one of u guys could explain.
I try to do some test on z-depth compositing and here it goes:
-
Rendered maya scene in *.iff (RGBZA) but combustion crashes when i about to open it.
-
Rendered maya scene using *.sgi(RGBA) and for the Z channel, maya rendered it as a separate *.iff file.
-
Brought the two file in sucessfully as footages but could not make it work under the compund blur footages.Is this because the Z-depth channel that was rendered as *.iff file is not a image?
-
Then I previewed the Z_depth channel under fcheck and saved it as image file *.sgi.The results turn it into blue and green mixed color image and not grayscaleand (only g+b channel contains “values”). Brought the image file in and used it with the compound blur and it works,(luminance,green,blue,value)
-
So could any of you guys comment on how to use the true Z-depth channel creating depth of field effects?And I tried the “simulated Z-depth map” technique and how accurate is it compare to the true Z-depth?
Thank You.
