Fast Snow earns its place in the superhive library for a focused, reversible approach: one click inserts a snow node into every material, and Remove Snow clears it back out. It is MIT-licensed and covers Blender 4.5 through 5.0 on both Cycles and Eevee.
Fast Snow is a Blender add-on from CITIGEN that turns a scene into a winter look with a single click. Instead of building a winter version of the textures on your objects, it searches through all your materials, inserts a snow node, and reorganizes the surrounding nodes to fit.
The conversion is reversible. A Remove Snow option strips out every node the add-on added, clearing them cleanly when you no longer need the effect. It is described as especially useful for scenes packed with objects, or complicated geometry-node-based scenes where there is no apparent shader information to edit by hand.
It works with both Cycles and Eevee and supports Blender versions 4.5 through 5.0. The add-on ships under an MIT license and includes documentation and product updates from CITIGEN. A demo video is also available.
Fast Snow is best for adding snow to scenes with a large number of objects, or complex geometry-node-based scenes with no apparent shader information, across Cycles and Eevee.
Fast Snow is completely free to download and use.
Fast Snow supports Blender versions 4.5 through 5.0, so it fits recent releases of the software. It runs with both the Cycles and Eevee render engines, meaning the winter conversion applies whichever of the two you render in. If you work across a range of projects within that version span, the add-on covers them. For the most current version details, check the developer's page before installing, since supported releases can shift as Blender itself updates.
Fast Snow works with both Cycles and Eevee, the two render engines listed for it. The add-on inserts a snow node into your materials and reorganizes the surrounding nodes, and that setup applies across either engine. Because it operates at the material level, you can convert a scene and render the winter result in whichever of the two engines your project uses. Check the developer's page for any further detail on how it behaves per engine before you commit to a workflow.
Fast Snow includes a Remove Snow option that clears the snow nodes it added, cleaning them all out when you click it. This means the winter conversion is not a one-way change; you can apply the snow effect across your materials and later strip it back out. It pairs with the one-click conversion that searches through every material to insert the snow node, so the add and remove steps mirror each other. For a walkthrough, a demo video is available.
Fast Snow is described as especially useful for scenes with a massive number of objects, or complicated geometry-node-based scenes with no apparent shader information. Rather than editing each material by hand, it searches through all your materials to insert a snow node and reorganizes the surrounding nodes. That makes it aimed at cases where manually preparing a winter version of every texture would be impractical. For a look at it in use, a demo video is available on the developer's page.
Fast Snow is listed as free in this catalog. It ships under an MIT license, and the entry includes documentation and product updates from CITIGEN. The MIT license is a permissive open-source license, which is worth confirming against your intended use before you rely on it. For current licensing terms and any support details, check the developer's page directly, since these can change over time and are best verified at the source.
