[SOLVED] Missing piece of puzzle with auxiliary pass

[danni.coy]

I have material with the auxiliary pass set to default.

I have an auxiliary colour defined in the material.

I can see this colour in a buffer when I press 5.

How do I get it this to overlay my mesh in the main veiwport?

 

[edit] solved

one has to

1) make sure that auxilary is enabled in render settings (esc key menu).

2) create a child material of render_composite. set the auxilary to overlay.

3) use the render settings to add that material as the composite shader.

I've added cross-links into docs to make this more transparent.
