Finding the Material Parameter Name

You can specify material parameter names for some Script Canvas editor nodes. In the Material Editor, you can find the material parameter names in the following sections:

Opacity Settings
Lighting Settings
Shader Params

You can find common parameters in the Opacity Settings and Lighting Settings sections. You can find parameters that are specific to the selected shader in the Shader Params section.

[Find material parameter names in the Material Editor in Lumberyard Editor.]

To find the material parameter name

In Lumberyard Editor, choose Tools, Material Editor.
In the Material Editor, navigate to the material file.
In the Opacity Settings, Lighting Settings, and Shader Params sections, pause on a parameter to find the script parameter name.
Example
For Diffuse Color (Tint), the script parameter name is diffuse.

Example
For Emittance Map Gamma, the script parameter name is EmmitanceMapGamma.

The following parameter names are commonly available and built in all materials.

Param	Type	Display Name	Description
opacity	Float	Opacity	Sets the transparency amount. Uses 0 to 99 to set Alpha Blend and 100 for Opaque and Alpha Test.
alpha	Float	AlphaTest	Uses the alpha mask and refines the transparent edge. Uses 0 to 50 to bias toward white or 50 to 100 to bias toward black.
diffuse	Color	Diffuse Color (Tint)	Tints the material diffuse color. Physically based materials should be left at white.
specular	Color	Specular Color	Shininess and color of reflective highlights.
shininess	Float	Smoothness	Smoothness or glossiness simulating how light bounces off the surface.
emissive_intensity	Float	Emissive Intensity (kcd/m2)	Brightness simulating light emitting from the surface, making an object glow.
emissive_color	Color	Emissive Color	Tints the emissive color.
