Light Material Function

Because my environment has water reflections in it, I thought it would be useful to create the Light Material Function featured in this tutorial video.

While I didn't end up with the exact same result due to different available assets, I did find a substitute tiling noise texture that worked just as well.

Here is my version of the water ripple Light Material Function:



As you can see, my noise is colour, but it doesn't reduce the effect that I wanted. I'll just have to tweak the colour in the actual light.

I found this information very useful both with creating materials and using material functions in lights.

I decided at a later point that the effect wasn't scattered enough, so I returned to this material and added a few more noise layers and multiple scroll directions to increase the surface scatter to the point I was happy with.
