Water

(The real Billster) #1

I know how to make water(create a brush texture it with water but if you want to fit the water in an irregular shape (not a square how would you do this?

Overlap your ground with the water and/or make your water out of multiple brushes and use nodrawwater on the parts that don’t make up the surface.

(Prophesy) #3

Ah a major breakthrough occured tonight when I finally figured out how to get the foam effect on water seen in Battery. Probably not news to most of you, but for one who is not that familiar with shaders it was a religious experience. To say the least :smiley:

But there was a reason for sharing this with you. I now need to figure out how to edit the direction in which the foam is moving…

I assume the answer to that question might be hidden in these lines somewhere? Does anyone know which numbers to change to change direction of foam-waves?

I would play around with the ‘tcMod turb’ and ‘tcMod scroll’ lines of the seawall_foam stages. For definitions on what these do, see the shader manual.
