Light affecting water textures

[napalm_death8]

I was wondering if anyone knew if there was a way to make a light spot that could affect the color and brightness of water, like on this picture:

Does anyone know? Please tell me!!

I do not understand what you are asking or what we are supposed to be seeing in that image. Care to expand?

I'll try it for you and see what I can come up with.

I tried my early-morning hardest with a custom lighting model, but those need a significant amount of math and knowledge and honestly, I'm not a mathematician. I'll leave it to the experts on this one.

ue3 is supposed to support 'lightmapped' lit transparency. So if you setup a static mesh with forcelightmapping, and make a material with the blendmode set to translucent, and the lightingmodel set to phong.

Note: this will only display correctly AFTER you have built lighting. When viewing it in the mat editor, or in the scene without built lighting, it will not display correctly.

Also dynamic lights will not affect the material...

Question: does the lightmapping support specular highlights?

What I meant is that, for example, if you put a large sheet with a water texture on it and you put a light just above it, the water, at first, will be illuminated by the light, but when I do a full build, the effect of the light on the water texture goes away, and that's the problem, specifically. I would like to keep the light effect on the water texture just to give an effect that the sun is illuminating the water, like the picture on the link I put above. Another example, in Onyx Coast, if you look at the sun, you can see it's illuminating the water with a yellow/orange tint, which gives a very spectacular effect. I would like to recreate this effect.

If you look at Hourences outdoor water tutorial he sets up a part of the material to reproduce a sun spot on the surface of the water.
