I am fairly new to Irrllict and I am still trying to figure out how to use shaders.
Is OnSetConstants called once per frame update? Previously I had some MDX code that would set shader constants and update the vertex shader multiple times per frame update. Is it possible to do this?
Apart from the samples there seems to be very little documentation on the architecture of Irrlicht and how each interface behaves with another.
Maybe you can call "render()" more then once? Im not sure if this calls the shaders more than once though...you can never be sure with irrlicht Also if you need to which pass you are at just pass the shader a variable for the pass number like in a for loop with render() in it or something.
