This class allows you to define a custom shader program that can be used by a [ShaderMaterial]. Shaders allow you to write your own custom behavior for rendering objects or updating particle information. For a detailed explanation and usage, please see the tutorials linked below.

[b]Note:[/b] [code]param[/code] must match the name of the uniform in the code exactly.
|
|
[b]Note:[/b] If the sampler array is used use [code]index[/code] to access the specified texture.
