I was wondering if there was a way I could have two overlapping textures fade in to one another on my geometry.

ie sand, then fade into a second uvtexture of rocks

found a few posts but they all go back to like 2004 and all the links are dead and advice not relevent to houdini 11 at uni

Ideally id like to scult say a ditch and have the rocky texture at the bottom and sand on the top and them merge on the edges.

I can apply different materials use the material sop and grouds to the geometry but there is no merge, just texture 1, texture 2 squares
