Khronos public bugtracker – Bug 86
Equation shown for <constant> FX incorrectly contains <ambient>
Last modified: 2014-01-07 10:23:09 PST
The <constant> shader does not have an <ambient> child element, but it is mentioned in the equation describing its result - color = <emission> + <ambient> * al
This should just be "color = <emission>"
