How do I layer two displacement maps? I have one which I want to use for a tarmac surface and one that I am animating via dilateerode in COP's to gradually produce cracks in the tarmac.

Thanks for any help…

I seem to have mnaged it by layering two displacement maps after the dilateerode with an over node in COP's. Is this the usual method? Cheers.

As long as it works for you, it doesn't matter what is the usual method.

If you have two maps, you can use the VEX Displacement Layers shader to layer them.
