Material Shaders


There are five types of materials in OctaneRender™ currently.


Diffuse Shader

Diffuse materials have the following parameters to adjust:


Glossy Shader

Glossy materials have these parameters to adjust:


Specular Shader

Specular materials have these parameters to adjust:


Bump / Normal

Both the Bump and Normal channels can load images to control the amount of bump mapping and normal mapping (respectively.) The Bump channel should be set to floatimage to load a bump map. The Normal channel should be set to the image data type to load a full color normal map.


MaterialThe representation of the surface or volume properties of an object. Mixer Shader

The Material Mix option is used to combine two different materials. It accepts any two material nodes and the mix is controlled by a texture node. In the example below, a white glossy material is mixed with a red specular material. A checks texture node is used to control the mixing of the two materials.


Light Portal shader

A portal is a special material applied to a plane to allow the render kernel to efficiently find openings / windows in interior renders. The use of portals will be covered in the section covering lighting options.
