NeutrinoParticles Editor 2.0.11 is out, together with updates across the runtimes and the website.

2.0 was a big release; this one is about living with it. Three things stand out: updating the editor no longer deletes your files, the interface now speaks Chinese, and the Emitter Guide can drive any 3D value with noise, without touching the scheme.

Updating no longer takes your effects with it

This is the important one. Until now an automatic update cleared the whole editor folder before unpacking the new version — so if you kept effects in there, next to the bundled samples, they went with it.

The editor now knows which files are its own and removes only those. Anything of yours in that folder is left alone. Updating from an older version still has to clear the folder, because those versions never left such a record — the editor warns you first and lets you cancel and move your files out. Either way, the bundled samples are always replaced, so if you have edited one, save it under a different name.

The editor speaks your language

A Language setting in Editor Settings switches the interface between English and Simplified Chinese, and by default the editor follows your system language. The whole interface is translated — menus, dialogs, the block palette and scheme, the Emitter Guide, block properties, the graph editor.

Block tooltips deliberately keep the original English block name alongside the translation, so Chinese users can still follow English documentation and video tutorials. A Chinese font ships with the editor, so the interface reads correctly on any system. Your effects are untouched: names, presets and exported code stay exactly as they were, and a project saved in one language opens identically in the other.

A new Noise value in the Emitter Guide

In the Emitter Guide, any 3D value — a colour, a size, a position offset — can now be driven by a 3D noise field. You pick Noise from that value's type menu, the same menu you already use to switch a value between a constant, a random range or a graph. No scheme editing needed.

By default the field is sampled at the particle position, so it reads as a coherent field in space rather than as per-particle randomness: particles near each other get similar values, and drifting through the field makes them flow. Smoothness, animation speed and output scale are all exposed, and the scale can itself be randomized or animated.

Elsewhere in the editor

The path editor gained a Reverse Direction button, which flips the direction a path runs in while keeping its exact shape, Bezier handles included. The Emitter Scheme canvas is now darker than the panels around it, so the scheme no longer blends into its neighbours. The interface font now looks the same on Windows, macOS and Linux, which it previously did not. And the editor no longer gives up on itself during an ordinary slow moment — such as a file dialog opening a folder on a network drive — instead of costing you the session.

Runtimes and exporters

PIXI v8: effects are drawn in the right place again. Anything added to the stage before an effect was being painted on top of it instead of underneath, so the effect looked stuck behind the scene.

GPU renderer: the preview now matches the exported effect where it used to differ — very bright particles are capped the same way in both, and values driven by system time animate correctly at particle construction instead of staying frozen.

The Cocos Creator and MonoGame packages, and the JavaScript, C# and GPU exporters, are all refreshed alongside this release.

On the website

Signing in and signing up were mangling passwords containing certain characters, which is why the site would sometimes accept a password that the editor then rejected. That is fixed. Registration links, which are single-use, now explain themselves instead of showing a bare error when clicked twice, and a fix to the site's scripts now actually reaches returning visitors rather than sitting behind a stale browser cache.

The documentation has new pages for the Noise value type, the language setting and the path Reverse Direction button.

Stability

This release also clears out a run of crashes: opening an effect that contains a mirrored emitter, switching between GPU effects, changing the dimension of a multi-row value, and editing in the Emitter Guide while the panel refreshed underneath you. Along with those, a half-typed value name is no longer silently saved when the panel refreshes. The release notes describe each one in detail.

Getting it

2.0.11 is available for Windows, Linux and macOS on the downloads page. The JavaScript and C# runtimes update through npm and NuGet as usual.

If you hit something odd, tell us — crash reports carry the effect you were working on, which makes a report far more useful than it used to be.
