how to mix two build in shaders

I was wondering were I would find the code for the built in shaders. I want to mix the transparency shader with the self illumination one, and was wondering if there was a way to do this or if some one had already done it.


The particle shaders are transparent. They are not technically self-illum but rather unlit. Which do you actually need? What is the object this shader is for? A glowing forcefield, for example, is transparent unlit, so one of the Particles shaders would be used for it.

Meshes can have multiple materials. See here
