The Shader node
Shader Node Introduction
The Shader node can control the lighting, reflection mapping, and 3D shading of elements in a
rendered image. The node relies on the presence of the normal map channel in a rendered
image. If this channel is not present, this node has no effect.
Inputs
The Shader node includes three inputs: one for the main image with normal map channels, one
for a reflection map, and another for an effect mask to limit the area where the depth blur
is applied.
Input: This orange input is the only required connection. It accepts a 2D image that
includes a normals channel.
Reflection Map Image: The green reflection map image input projects an image
onto all elements in the scene or to elements selected by the Object and Material
ID channels in the Common Controls. Reflection maps work best as 32-bit floating
point, equirectangular formatted images
Effect Mask: The optional blue effect mask input accepts a mask shape created
by polylines, basic primitive shapes, paint strokes, or bitmaps from other tools.
Connecting a mask to this input limits the shader to only those pixels within the
mask. An effects mask is applied to the tool after the tool is processed.
Basic Node Setup
The Shader node is inserted after a 2D image that contains a Normals channel. Below, a
Renderer 3D is used to add a Normals channel to an image. The Shader node uses the normals
for refining the surface appearance with a reflection map connected.
