ðŸ’Ĩ Niagara Editing

Ludus edits Niagara systems from the Ludus chat in the plugin window inside the Unreal Editor. It adds, removes, and reorders modules, and modifies emitter, renderer, data interface, and user parameters. It can also assemble a full system from a description so you tune parameters instead of building the stack by hand.

This removes the manual assembly of emitters, module stacks, and renderers in the Niagara editor.

How to use​

  1. Open the Ludus plugin window in the Unreal Editor (Unreal Engine 5.4 to 5.8).
  2. In the Content Browser, open the Niagara system you want to change, or reference it by name in the chat.
  3. Type your request in the Ludus chat, naming the emitter, module, or parameter to change.
  4. Review the staged module and parameter changes. Example prompt: "Build a campfire Niagara system: an upward flame emitter with a sprite renderer, and a slower smoke emitter above it." Expected result: Ludus assembles the emitters, module stacks, and renderers, sets starting parameters, and stages the system for approval so you can tune it.

Editing an existing system​

  • Add, remove, and reorder modules in an emitter's stack.
  • Modify emitter, renderer, data interface, and user parameters.

Generating matching materials and textures​

Ludus can generate matching materials and textures alongside a system. See Material Editing for material work and Images for texture generation.

Options and limits​

  • Edits cover modules (add, remove, reorder) and emitter, renderer, data interface, and user parameters.
  • When Ludus assembles a system from a description, treat the result as a starting point and tune the parameters.
  • Describe the effect and behavior you want rather than exact per-frame values.

Approvals​

Ludus will ask you for approval before making edits. See Approvals & Safety.
