How do you create custom shaders and environmental effects in T3D?

I was trying to apply a custom shader for an "lightning effect" in T3D, similar to:
www.youtube.com/watch?v=f6-H3AkNd6o (since it uses DX9, too!)
and was wondering if this is a good place to start:

Actually all the effects covered in this PDF, would be nice to see in T3D. So I was wondering if someone with more experience in the custom shader area would help me achieve this effect.

Thanks

You mean ... a lightning object that uses a light flash?

Couldn't you do that with a scriptObject that turns an animated light on at a source location (where the lightning comes from) which is synched to a thunder noise, and then turn it all off when the lightning strike is over?

If you're just doing things inside a building, you could just slap these lights around the windows and trigger them all enmasse.

That would be a nice way to do it, but I wonder if a method using shaders would have a more professional look?
Plus some of the other effect I'm quite sure would have to be done using shaders.
I also noticed other game engines using DX9 have had success going with the shader method.

During my research I came across a couple of PDF's for applying environmental effects like: wet surface material, volumetric clouds and lightning, and other effect that would be awesome to see in T3D! My question is are this a good place to start? From talking with different shader experts, T3D render system is the key but I don't know enough about it. So if someone with more experience can "chime - in" maybe we can get a community project going to implement some if not ALL these effects.

Here is another whitepaper for lightning that maybe helpful
