I have this terrain and I added a material which is called "Freshly Dug Grave". Now I want to add another material under it called "Eroding Cliff". How do I do that? I know that if you select the diffuse button it adds another material underneath it to Texture B, but how can I get a material from the main materials list instead of the ones they have in that drop menu on the top right. If I select the preview on the left and select the material I want, it changes Texture A into it instead of texture B. Anyone know how to do this? Thanks again.
