Need help pulling layers from texture bakes.

So say I have a texture like the one pictured above. It's essentially one type of material on top of another. In this case, rocks over top of sand. What is the best method to texture the rocks in one layer and the sand in another? I've always just outlined them in PS by hand... And man, I am sick of dong that.

I'm sure there are several ways to approach this, so I'd love to hear of some methods from my fellow Polycounters.

If you're rendering the texture from a highpoly source you can just render the elements with different colours and use the colours as masks. That's what I'll usually do.

Just pointing this out: looks like your normal map didn't have the rays cast far enough as it's missing the tops of some of your rocks
But like Sprunghunt said, make the sand black and the rocks white and render a diffuse and its all set to go. Instant mask!

Use the power of SRGB my boy...or ARGB...which ever color code you like, no pressure just saying.

No worries, I fixed it already! Accidently grabbed the wrong one to upload. And thanks for the replies guys, rending out masks seems the way to go.

if you can render it, you must not click it
