#Overview

name: r.Shaders.AllowUniqueSymbols

The value of this variable can be defined or overridden in .ini config files. 2 .ini config files referencing this setting variable.

This variable is created as a Console Variable (cvar).

• type: Var
• help: When enabled, this tells supported shader compilers to generate symbols based on source files.\nEnabling this can cause a drastic increase in the number of symbol files, enable only if absolutely necessary.\nThis setting can be overriden in any Engine.ini under the [ShaderCompiler] section.

It is referenced in 2 C++ source files.
