/*******************************************************************************************
*
* raylib [shaders] example - Simple shader mask
*
* This example has been created using raylib 2.5 (www.raylib.com)
* raylib is licensed under an unmodified zlib/libpng license (View raylib.h for details)
*
* Example contributed by Chris Camacho (@codifies) and reviewed by Ramon Santamaria (@raysan5)
*
* Copyright (c) 2019 Chris Camacho (@codifies) and Ramon Santamaria (@raysan5)
*
********************************************************************************************
*
* After a model is loaded it has a default material, this material can be
* modified in place rather than creating one from scratch...
* While all of the maps have particular names, they can be used for any purpose
* except for three maps that are applied as cubic maps (see below)
