good tutorial.
It has all steps I have made for a german forum for the same tutorial theme. But your's are quite better because it's visual.
some additional infos:
You can instead of defining the Pass1 material as "Environment" also use e.g. "Linear Offset" with attributes like UPerSec=1.0 / VPerSec=-1.0 etc. which moves the texture along the coordinates.
Multipass materials don't really allow 2 or more passes which all use AlphaBlend methods (or any other transparency mode afaik).
This method also allows you to make you night models with bright windows. If the building already uses the mirror effect that GuyInTheWindow described here you just add a Pass 3 which use Add shader and has a black texture of your building texture where only the parts of the windows are bright. The other steps are similar to those of this tutorial.
@ GuyInTheWindow
Do you also know how to animate textures (without animating the meshes itself) ?
To see an example of what I mean look at the blinky lights which are on some maps of ZH. I mean these red and blue lights which can be placed on ground...
I'd like to know how to create such pulse effect of the lensflare texture. I never got it.
