◆ getShader()

u32 ShaderSource::getShader	(	const std::string &	name,
		const ShaderConstants &	input_const,
		video::E_MATERIAL_TYPE	base_mat,
		IShaderUniformSetterRC *	setter_cb = nullptr )

overridevirtual

Generates or gets a shader.

Note that the input constants are not for passing the entire world into the shader. Use IShaderConstantSetter to handle user settings.

Parameters

name	name of the shader (directory on disk)
input_const	primary key constants for this shader
base_mat	base material to use
setter_cb	additional uniform setter to use

Returns: shader ID

Note: base_material only controls alpha behavior
