Serpens is a node-based visual scripting environment for Blender that allows users to create installable Python addons without writing code. It enables the creation of custom user interfaces, including dedicated panels, buttons, and pie menus, to streamline specific workflows. The tool features a visual node editor where users can construct interactive modals and interface elements that integrate directly into the Blender UI. It also provides tools to incorporate custom Python code and view the generated scripts, serving as a stepping stone for learning the Blender API. Serpens includes capabilities for interacting with geometry nodes and auto-compiling scripts.
