Get Specular Colour
Due to advances in Terragen’s rendering architecture, this node is deprecated and no longer supported.
Overview
Provides the "Specular Colour" of the current Render State. The Render State is affected by any shaders which were called before this function is called, among other things.
The input connection is not used by this node (consistent with all Get nodes).
Specular Colour is the additive component of the appearance of a surface which was reflected from light sources by an amount that strongly depended on the viewing angle, surface normal and light direction. Usually this comes from "specular highlights" settings in the GUI. It is not the specularity of the surface, but the final specular contribution at that point. Currently, ray traced reflections and transmissions are not stored in the specular component, but this may change in future.
Settings:
- Name: This setting allows you to apply a descriptive name to the node, which can be helpful when using multiple Get Specular Colour nodes in a project.
- Enable: When checked, the node is active, and when unchecked the node is ignored.
