Node-based Visual Effect Graph system (VFX Graph)

[erenster2000]

Motivation

Godot currently provides a Visual Shader Editor and particle systems, but does not offer a unified, node-based workflow for creating complex visual effects.

Use Cases

• Creating advanced visual effects for gameplay, UI, or cinematics without custom scripting.
• Offering an accessible workflow for technical artists and designers.
• Attracting users familiar with other engines that provide similar tools.

Feature Overview

The idea is to implement a node-based editor dedicated to visual effects, supporting both GPU and CPU particles, with a drag-and-drop interface, modular node system, and real-time preview capabilities.

Open Questions

• How should such a system integrate with Godot’s current rendering and particle systems?
• What are the main technical challenges and limitations?
• Are there existing community plugins or prototypes that could serve as a starting point?
• What features would be most important for users?

Additional Notes

I do not have a detailed technical implementation plan, but I believe discussing this idea and gathering feedback from the community could clarify the requirements and feasibility. If anyone is interested in prototyping or has relevant experience, please share your thoughts!

supporting both GPU and CPU particles

CPUParticles are purely fixed-function (they can't be scripted in any way), so this is only feasible for GPUParticles.
