Snowstorm review
A focused, free editor for designing and previewing Bedrock particle effects.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Snowstorm is a free, open-source editor for Minecraft Bedrock Edition particle files. It is aimed at creators working on particle effects for resource packs, especially those who want visual controls alongside direct JSON and MoLang editing. The web application provides a 3D live preview, while the Visual Studio Code extension supports *.particle.json files. Its scope is deliberately narrow: it focuses on particle effects rather than general add-on, entity, block, or scripting development.
The editor’s strongest area is its hybrid workflow. Visual controls cover emitter and particle parameters, while generated-code preview and direct code editing give users a closer view of the resulting file structure. MoLang expression editing supports more precise particle behavior, and custom particle texture loading helps creators work with their own visual assets. Import and export of particle JSON files also fit existing resource-pack workflows without requiring the editor to replace a broader development environment.
Snowstorm is a good choice for Bedrock creators whose main task is building, inspecting, and previewing particle effects. Its web availability lowers the barrier to accessing the visual editor, while Visual Studio Code integration suits users already editing particle JSON files there. It should not be the primary choice for a complete Minecraft add-on workflow involving custom entities or scripting. For those needs, a broader editor would be a better fit; for particle-focused work, Snowstorm’s focused toolset keeps the workflow centered on the relevant files and previews.
Snowstorm pros and cons
- Where it wins
- Live 3D preview helps visualize particle effects while editing.
- Hybrid visual and code editing supports emitters, parameters, and MoLang.
- Imports and exports particle JSON files with custom texture loading.
- Where it doesn't
- Focused on particle files rather than complete add-on development.
- No custom entity tools for broader Bedrock content workflows.
- No scripting support for add-ons that require script development.
