Blend node?

[gregtee]

Is there a blending node in terragen?  I want to blend two different cloud nodes together based on an alpha channel image and I can't seem to find anything that'll do this.  Sort the equivalent of an Over node in a composite program. 

I'm sure it's there but it isn't obvious to me

Thanks!

There's the merge shader to mix nodes. But it seems you can more easily (inversely) blend the fractals of the clouds by the image map.

Thanks Dune, I found the Merge scaler mix node.  Did exactly what I wanted it to do.
