Here's an experiment I'm doing in Houdini. It's an attempt to make my own Metallic paint shader. It was done for the purpose of learning to build shaders from scratch within Houdini. I'm not totally satisfied with the result, but I think it looks ok. I still feel like I'm missing a really important piece, which is moving sparkles when angle of view changes. This is the next step. Enjoy!
