:alt: Flowchart showing the entire compilation process for a shader: VisualShader and Standard Material to Godot Shading Language to GLSL to Intermediate Format (SPIR-V) to Pipeline. Shader Compilation is the GLSL to Intermediate Format step. Pipeline Compilation is the Intermediate Format to Pipeline step.
Shaders and materials in Godot go through several steps before they can be run
by the GPU.
In more precise terms, *shader compilation* involves the translation of the GLSL
code that Godot generates into an intermediate format that can be shared across
systems (such as SPIR-V when using Vulkan). However, this format can't be used
