Combined Passes/Layers Problem

Support Compositing and Post Processing

Hi,

I appear to be having an issue trying to combine my passes/layers to create an image. Idealy I wish to output the files individually so I can adjust them in Gimp.

I’ve follwed the details on the Blender wiki for this, although I may have got something wrong:

This is what I created to test, but as you can see it comes out as a greyscale image. The Diffuse Colour seems to get lost from the start.

Any help would be appreciated :slight_smile:

Jay.

P.S. sorry for the layout, it’s not easy to keep such a tree tidy.

After Bartek pointing out my silly mistake, here’s the correct method :wink:

Don’t use “Math” nodes, but “Mix” nodes with proper blend types.

Thanks Bartek,

I’m sure I’m not the only one that gets them mixed up - least I hope not :wink: All sorted now!

Just look at the colors of sockets. Gray means that it’s a value, so it passes just a single figure. You’ll get just a grayscale image. Yellow means Image. Yellow socket can pass 4 figures, i.e. R, G, B and Alpha.
Math node has gray output, so it doesn’t handle images.
