Core It is used to create a unstable, reflecting and refracting core of energy, used exclusively for the Core reactor in the Citadel in Episode One.
Note:In order for this shader to work properly, it must be used with a prop_coreball at the position of (2688,12139,5170). This value is hardcoded into the shader.Note:This shader does not exist in engine branches after the Orange Box.Shader Parameters
