ProtonGraph: Procedural 3D Content Creation in Godot
ProtonGraph is a node-based software designed for procedural 3D content creation using the Godot Engine. It empowers users to create complex 3D models by connecting simple nodes, offering a visual scripting approach tailored for 3D model generation.
Key Features and Goals
The primary goals of ProtonGraph are ease of use, extensibility, and a focus on game development. The tool aims to enable content creation in advance or real-time content generation within games. Being open source under the MIT license, ProtonGraph promotes flexibility and avoids legal complications.
Current Status and Roadmap
Currently, ProtonGraph is transitioning from Godot 3 to Godot 4. While some features are temporarily unavailable or undergoing refinement, the core porting process is largely complete, with ongoing efforts directed toward stability and content enrichment. You can track progress on the project board. The project can be built manually from source using Godot 4.
