ShaderFX Custom Code sample for Maya 2015, maya LT

SFX_hqCustomCodeTest

// You may add new struct outputs, function inputs and adjust code in the function. 
// Function name and output struct should match 'Function Name' attribute on node. 
// Available preprocessor definitions: SFX_HLSL_3, SFX_HLSL_5, SFX_GLSL_1_2, SFX_GLSL_4, SFX_CGFX_3, _MAYA_, _3DSMAX_, SFX_SWATCH 
// You can use SFX_TEXTURE[n] or SFX_SAMPLER[n] to refer to texture inputs so you do not have to hardcode their names
