It is perhaps a bit premature to mention this here, but there is already an authoring software called Sunrize based on X_ITE, which of course simplifies the creation of scenes that also supports ParticleSystems.<div><br></div><div>Sunrize: <a href="https://www.npmjs.com/package/sunrize">https://www.npmjs.com/package/sunrize</a></div><div><br><div>
