HLSL conditional compile #define in Maya?

[Anonymous]

3DS Max defines #define _3DSMAX_ when it loads(and compiles) a HLSL shader. As a result, we can do something like this in shader codes:

#ifdef _3DSMAX_
    float4x4 World:WORLD;  //USE SAS in Max
#else
    float4x4 World(c36); // Use predefined constant register in Game
#endif 

Is there any equivalent keyword Maya 2009 defines while compiling a HLSL shader?


Thanks,
