Thanks for reporting this!
You'll find a fixed version of the node here: https://pastebin.com/raw/6ak8CD7w
You can either copy the text from that address and paste it into Material Maker's graph view, or just copy/paste the address (Material Maker will download the fixed node unless your firewall prevents it).
It works! Thank you! I'll save it to my user library. By the way, is there a way to upload nodes on materialmaker.org? I translated a setup from Substance to make endless textures with an atlas (and trying to make a shader in godot for them). I think I'll upload it as a material to demonstrate it but would be cool to have a section to browse custom nodes, especially ones that generate noise or patterns
