Hi Guys,
I want to present you something that I've been working on for a while.
Creating, especially layering shaders isn't always easy and can be quite confusing,
so I started my own plugin to emulate Substance Designer's workflow.
Now you can easily drag all your noises, pattern etc. into the xpresso pool, connect it to the py script and that to the channel you want to map.
You can blend, normalize, change curves/HSV, drag-transform and much more with the provided nodes. It also features an interactive 2D preview of the selected node and it works very well with IR.
Notes & how-to are provided in the scene file
Give it a try and tell me what you think!
