[c#.net] Directx Question

[royteusink]

 Haay Haddd Team,

I have a question about fx shaders :blink:, How can i apply this shader to model / texture??
Please help i can't figured it out :(
It returns a black vertex :S

The fx file works with FX Composer from Nvidia.

effect.Commit

device.DrawPrimitives(PrimitiveType.TriangleList, 0, 1);


This could be a problem, you are not using commit. But i think this is not the forum to solve these problems, it's focused only on the engine.

[royteusink]

 effect.Commit Doesn't excist but okey, it still doesn't work..., is there a forum where i can ask this sort of questions?

Sorry, but it's no so easy take your code and give you a fast response.
