Water shader for rooftops

[Lux]

I would have liked to post this in the thread that had the upgraded shader that was created for windows where the water is running down the windows. Its likely? that we could use the window running water on roofs to get this effect but it would have to be scaled up.

 

In Thief there is a shader with water sheeting down the roofs. It almost looks "veiny" and a bit like honeycomb in places because of the eddies flowing together from the sheeting action of water down the roofs.

 

 

 

There are actually 2 different shaders going on here so I tried to highlight the water streams at the edges of the water sheets and the obvious direction of flow down the roof to make it more clear what the shader is. The water droplet impacts/ripples (circular) are the shader so disregard that effect in these shots. If you look closely you can see the ridges of water running down the roof.

 

It could also be used in sewers where there are run-off concrete/brick slanted angles that water is cascading down.

 

Its a shame there was really only one Thief mission, "Lockdown" with rain in it like this as the effect is really cool.

 

Could one of the shader gurus here create something like this for TDM?

Looks a tad overdone in Thief, but it would be nice to see something similar....but toned down.

I guess you could start with the shader created by Arcturus. Using a different scale and tuning the bumpiness may do the trick. Maybe I will find the time to look at this tomorrow.

 

Btw.: Imho the look of it appears only overdone in this still images. In game it never appeared that strong to me.

Thats a very good idea, mixing that with having some water running off the edge would look fantastic.
