Sometimes, you want the same shaderA program that runs on the GPU. More info
See in Glossary to do different things under different circumstances. For example, you might want to configure different settings for different materials, define functionality for different hardware, or dynamically change the behavior of shaders at runtime. You might also want to avoid executing computationally expensive code when it’s not needed, such as texture reads, vertex inputs, interpolators, or loops.
You can use conditionals to define behavior that the GPU only executes under certain conditions.
