Shading a landscape with Arnold Curvature

- [Instructor] The Arnold renderer provides helpful utility…and mapping nodes to extend the capabilities…of a 3ds Max shading network.…For example, Arnold can find the curvature…of a surface and map that information…onto a shading property such as color.…In this exercise, we'll use the Arnold Curvature node…to render the flat areas of this terrain…in a different color than the bumpy areas.…Along the way, we'll learn about the limitations…of the Arnold plug-in version one…and find workarounds to achieve our production goals.…

We'll start by opening up the ActiveShade window.…I've applied an Arnold Standard Surface material…onto this terrain.…Let's take a look at that.…Give focus to the main window and press M…to open up the material editor.…Here's the Arnold Standard Surface material for the terrain.…I want to start by adding a normal map…to introduce some bumpiness onto the surface.…And that's going to be a flakes map.…We'll find it in the Maps section under Arnold,…Surface...…

Flakes.…So drag that over.…And double-click it.…
