The Phong shader

The Phong shader

- [Instructor] You can add materials and textures to your 3D geometry using Nuke's shaders to achieve photorealistic renders. The Phong shader is the Swiss army knife of the shaders as it incorporates three shaders in one. To ease into it, we'll look at the diffuse shader first, then step up to the Phong shader. You may recall that if you add a texture map to a geometry with a light, you get an 18% diffuse shader but there's no adjustment. So, if we want to dial in our diffuse, we're going to have to add a diffuse shader. We come over to the 3D Menu, Shader, come down to Diffuse and we'll bring it here. Now watch what happens when I hook the geometry directly to the diffuse node. We lose our texture map and what we're seeing is an 18% diffuse render of the raw geometry, sort of a white billiard ball. Down here is our diffuse shader value, .18%. I can dial it down and dial it up or turn that back to default. If I connect an image to the map input, this becomes a texture map with an 18%…
