Unreal Tool Development

Canyon tool

The canyon tool is designed to create a large scale landscape efficiently. As video shows, one of the functions of this tool is that it supports multiple layers. I start to build this tool by analyzing the real world canyon.

The surface on the top

Using Vertex Normal to specify the top surface.

Multiple Layer at steep cliffs

Using Absolute World Position to creat layer.

World alines texture for layers.

Using world alines node to crate materials not affected by UV space.

Final Shader

Now, we got all the things we need, which are top surface specify shader, layer shader, texture laines shader. All we need to do is conbine them together, I convert them into saperite material function and using them in the final shader.
