Ambient occlusion pass and displacement maps

[LOAM]

I've been getting into displacement maps recently and whilst they speed up modelling I'm lost as to how to deal with the ambient occlusion pass as obviously overiding the material loses the displacement map.

How do you chaps deal with it?

To add, I know that I can add an AO pass within the render but I would ideally like to have control over it for post production. I've tried turning off the "maps" setting in global switches in the hope that it would retain the maps but it doesn't. Am I missing something here ?

You know - that would be a useful feature - to disable override material for bump & displacement per material. Chaos Group, is something like that possible?

@Loam - can't think of any way other than in your material editor: add a new diffuse layer below your main diffuse layer with the same color as the override material and mask your 1st diffuse layer with TexAlpha transparency for rendering the override only. Then switch the TexAlpha color back to black for your final render.

I think that's the only way Andy, its going to be a pain though to do for every material that has displacement hahaha, good job I have had a beer!
