Just copy and paste this code to the program.cs in the Shader tutorial.
Of course you need the ressources of TGMs ShaderPack in the medias
folder (get it here: rapidshare.com/files/28934132/TGMs_ShaderPack.rar.html ).
And here is the lava.hlsl (must be added to the medias folder:
Btw: PixelShader 2.0 is needed for this one. In GLSL (have a look at the original Shader pack) PixelShader 1.0 is required... Strange, or?!?
