RDPipelineSpecializationConstant
Inherits RefCounted
Pipeline specialization constant (used by RenderingDevice).
Description
A specialization constant is a way to create additional variants of shaders without actually increasing the number of shader versions that are compiled. This allows improving performance by reducing the number of shader versions and reducing if branching, while still allowing shaders to be flexible for different use cases. This object is used by RenderingDevice.
Properties
int constant_id = 0
int constant_id = 0The identifier of the specialization constant. This is a value starting from 0 and that increments for every different specialization constant for a given shader.
Variant value
Variant valueThe specialization constant's value. Only bool, int and float types are valid for specialization constants.
