Interacting with Shaders


You want to interact with a Godot shader from GDScript.


To access the uniform’s value from GDScript, you can use set_shader_param() on the object’s material property. If the attached material is a ShaderMaterial, then you can access it like so:

node.material.get_shader_param("param_name", value)

You can also change the value with set_shader_param().

For an example of this, see the Blur Shader recipe.
