I was doing some shader work earlier today, and noticed something quite odd in my opinion about how EffectHandle's work. Take a look at this line of code: EffectHandle.FromString("insert favorite parameter name") Now, the odd thing that I noticed, is that no where are the EffectHandles actually associated with any particular instance of an Effect. Which made me wonder, what exactly is going on behind the scenes here? Is the EffectHandle just some sort of fancy string wrapper?¿Or do they get automatically associated with the loaded effect when effect.begin(...) is called? Or are they bound the first time the effect.SetValue(handle, value) function is called? Oddly enough, the august sdk says: An EffectHandle object is used as a unique identifier for a specific effect. Methods that work with effects often require the effect handle object of the Strange that it would mention "unique" and "specific effect".
