Any idea of how to implement this custom shaders ingame? so far I remember that there is a waving flag shader in game that you could load it using the templates from deffiles and some other options in assman.

I've been looking around this templates and this ones are related to techniquesets and this others to the .hlsl files, the code doesn't seem to be very hard but there is some stuff that i've got no clue why is there...

Any ideas? easier way to get them ingame?
