The Phong shader

The Phong shader

You can add materials and textures to your 3D geometry using those shaders to achieve photo realistic renders. The phong shader is the swiss army knife of the shaders as it incorporates three shaders into one. To ease into it, we'll look at the diffuse shader first and 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% diffused 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 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 a 18% diffuse render of the raw geometry. Sort of a white billiard ball. Down here is our diffuse shader value, .18, 18%. I can dial it down and dial it up. I'll return that back to default. If I connect an image to the map input, this becomes a texture map with an 18%…
