Problems setting parameters in HLSL effect
Hi I'm trying to get a basic effect running in my engine, but I am having difficulties getting the parameters from my code into the effect. They seem to be sticking at the initial value. For instance I have added time to the glow EffectEdit sample and added a sin(time) term to make the glow pulse. It works fine in EffectEdit, but in my engine, the time sticks at the initial value of zero. I have verified this in the debugger, I am setting the correct value (via Effect.SetFloat) every frame, but in the effect file it stays at zero (even though Effect.GetFloat returns the value I just set). I am having similar problems with my transformation matrices. I'm setting my params outside begin/end render block so it's not the lack of calling CommitChanges (although I have tried that unsuccessfully). Any ideas? Could I have my device set up incorrectly? Are there any good resources/tutorials around for setting up basic effects? The MSDN documentation that I have found seems a little sparse... Thanks
