Our verdict on VFX Editor

VFX Editor is Thunder Engine’s embedded workspace for creating and editing game visual effects. It is aimed at Thunder Engine users who want to author particle effects within the engine, from emission settings through a real-time preview. The parameter editor covers emission quantity and frequency, trajectory, speed and direction, as well as lifetime, size, texture and transparency. Effects are saved as Visual Effect assets in the Content Browser and adjusted through a modifier cascade.

The workflow is organized around three modifier stages: spawn, update and render. Available modifiers include velocity, rotation rate, color scale and size scale, giving authors controls over how particles are created and change over their lifetime. This makes the editor a focused fit for effects built from particle settings and modifiers; it is not positioned as a general-purpose VFX tool for multiple engines. The documentation states that GPU simulation is not supported yet, so projects that require that capability should consider an alternative.

VFX Editor is open source and available as part of Thunder Engine, which is described as a free engine. The editor is not presented as a separately priced product, and the listed deployment options are desktop and self-hosted. It supports Windows, macOS and Linux, with documentation as the support channel. Choose it if Thunder Engine is already your target and you want an integrated place to author and preview effects. If your workflow depends on GPU simulation or an engine other than Thunder Engine, its scope is a poor match.
