| Internal database of built in shader include files. | ||
| </brief_description> | ||
| <description> | ||
| This object contains shader fragments from Godots internal shaders. These can be used when access to internal uniform buffers and/or internal functions is required for instance when composing compositor effects or compute shaders. Only fragments for the current rendering device are loaded. | ||

| <description> | ||
| Returns the code for the built in shader fragment. You can also access this in your shader code through [code]#include "filename"[/code]. | ||
