Subject: mental ray alpha channel
In the mental ray shader I am writing I am setting the alpha channel value when the image gets written as "rgba" "pic" the alpha channel doesn't contain the values I have set in my shader. Seems like the values are correct for certain parts of the output image. The incorrect values interestingly turn out to be equal to the red channel values of the output image?! Please help me!
