Realistic canal water

written by bikerdude

Summary

I created this water for Seeking Lady Leicester because up until then, The Darkmod didn’t have water that looked like it should at night. So what we have is as close as I could get to faking moving water reflections that reacted to nearby light sources.

Pretty Canal Water

Coloured, Murky, Reflective Canal Water

In a nutshell all the water is comprised of is a standard guis\underwater\underwater_blue_thinmurk.gui for underwater and a custom shader for the surface. I choose the custom shader, because every other method of using patches on the surface of the water never got close enough to the result I was after.

Custom water texture

What we have is 3 stages -

• Bumpmap - this provides sudo micro-waves to the surface of the water.
• Specularmap - this provides the reflections on the waves from nearby sources of light.
• Deform/heathaze - this was copied from the stock water texture (water_coloured) to provide the darkness to the surface of the water at night time.
