Snow Accumulation (nVidia Shader)

[Stelios_81]

Has anyone played around with the Snow Accumulation shader from nVidia's site ftp://download.nvidia.com/developer/SDK/Individual_Samples/DEMOS/Direct3D9/SnowAccumulation.zip?

The paper on the shader can be found here ftp://download.nvidia.com/developer/SDK/Individual_Samples/DEMOS/Direct3D9/src/SnowAccumulation/Docs/SnowAccumulation.pdf

There seems to be some Matrix calcs i'm not performing well. Each mesh i apply this shader to is "disapearing"! Same happens when i apply the shader on a mesh in FX Composer.

I'm starting to feel a bit dumb here, hehe
