Beginners

This page is a very basic toturial for shaders and materials and explains what ColorMatrix do.

Shaders and materials

Relation with GameObjects

Properties types

• Standard properties: Defined in the material file
• Per renderer: Defined with scripts

For example, the Sprites-Default has the main texture in "per renderer", so this material can be used in all GameObject because this texture is defined by the Sprite renderer component.

For a 3d object, the Standard material has a main texture standard (because materials are usually configured by another software). For this reason you may change manually the shader in each material.

ColorMatrix

When you add a ColorMatrix component, the script search in the ColorMatrixConfiguration file to find the current Shader (Sprites-Default for a sprite).

If the shader is found, the material of the rendering component is replaced.

ColorMatrix script need a specific shader because it use more variables.

V2

In the new version, ColorMatrix uses PropertiesController to target the renderer component.

Including ColorMatrix in your own shaders

There is a node for shader graph and amplify shader. If you create your own shaders in glsl, see Custom shaders page
