When I render my Primatte mask, sometimes the masked pixels become transparent, but other times I get a grayscale image on my Photoshop layer. Why does this happen and how can I control it?
• There are two ways to render out Primatte. You have accidentally chosen the second way. Both methods are shown below. Method 1- If you render out Primatte with the ‘Comp View’ mode showing, then you will get the expected result. This is your subject against transparent pixels, of course. Method 2- When you render out your Primatte mask with the ‘Mask View’ mode showing, then Primatte renders out a grayscale image. That’s great for additional editing if you know a lot about Photoshop. Otherwise, you will want to render with ‘Comp View’.
