The authors created Elemental Alchemist, a tool that helps users edit complex particle effects (like fire or smoke) by turning creative ideas into easy controls. It has two parts: a brush set that adapts to the scene and a control panel that shows important parameters in a more understandable way. Their tests with both beginners and experts showed it helped users better connect their artistic intentions to technical settings. This makes designing visual effects more intuitive and accessible.

Abstract
Editing particle-system visual effects (VFX) is vital for digital storytelling, but achieving controllable, art-directable results remains challenging due to their multi-dimensional nature. Given a large collection of parameters, users must find the ones relevant to their creative goals -- a task that requires a systematic understanding of the particle system and how parameters map to high-level intents, such as making a fire look angry. Elemental Alchemist is a generative interface that transforms user intent into contextualized controls for semantic editing of particle systems. The system introduces two components: a contextual brush palette that generates tools based on scene context, and a generative control panel that surfaces relevant technical parameters and abstracts them to generate mid-level semantic attributes and high-level conceptual controls. An evaluation with 10 novice and 5 expert VFX practitioners shows the system supported users in translating high-level creative goals into particle system parameters.
