View Full Version : PBR algorithms as nodes

I was in the process implementing a number of functions from this article by Jordan Stevens into lightwave nodes ( It's the simplest thing I've seen explaining PBR algorithms)
I got through a number of Normal Distribution and Geometric Shadowing functions before the holidays hit. If anyone finds it interesting, feel free to use them. This is a bit more technical than my usual efforts, but if you find them useful, feel free to support the effort by getting a copy of Howler, or Artist 2019.

You can find the nodes here. Just import them into Lightwave Nodal. All the nodes are combined in one node, for simplicity. Go to the bottom of the page.
