Syntax

void GLSLToDeviceCompatibleGLSL
(
    FAnsiCharArray & GlslCodeOriginal,

Remarks

Processes the GLSL output of the shader cross compiler to get GLSL that can be compiled on a platform with the specified capabilities. Works around inconsistencies between OpenGL implementations, including lack of support for certain extensions and drivers with non-conformant behavior.

Parameters
