Shader Mixer / Brickyard creating an RGB Mask

LZY

Hi All,

Has anyone had any luck creating an Iray Shader with an RGB mask?   

Specifucally I'm trying to create a shader that takes an RGB texture map as an input and have that drive 3 sperate materials within the shader.  In the past I've been able to do this with seperate Black and White masks as inputs for each of the materials (so 3 seperate image files) but I'm hoping to consolidate this down to a single map using each channel as its own mask.   

I'm coming unstuck becuase I can't seem to find a Get Component or Split RGB brick in the brickyard.    

As an aside, this may be user error but is there anyway to search for bricks by name rather than scrolling through 

Thanks
