Season Cache

by ItsThatNova

Season Cache keeps snow and ice blocks matched to the season Serene Seasons sets, and it produces a per-chunk snow map that distant terrain shaders can consume.

What it does

Serene Seasons alone only alters the season, so snow accumulates or melts through Minecraft's gradual random tick process, a change that can take several in-game days to show across a wide area. Season Cache reconciles the entire loaded world as soon as a season transition occurs, so winter snow and ice appear across the terrain at once and spring clears it.

The mod keeps a server-authoritative coverage map of snow for every explored chunk and streams it to connected clients. That map is what lets Distant Horizons, which draws terrain far beyond the vanilla render distance with its own geometry, show snow on distant chunks accurately. When no per-chunk snow record exists, a shader has no means of telling which far-off chunks should appear snowy. Nova Reimagined Snow handles the shader integration on the client, and the Nova Reimagined shader pack uses the data.

Season Cache works on dedicated servers and in singleplayer. A dedicated server needs only the server-side install, while a client needs the mod to run its coverage features. It requires Fabric API and Serene Seasons, and it is published for Fabric only, across 12 release versions 1.21 – 1.21.11, with 1.3.1 for 1.21.10 as the latest file. The mod is open source under the MIT License.

Key features

  1. Season-synced snow and ice

    Snow and ice blocks follow the season set in the Serene Seasons configuration, including when winter arrives and when spring clears them.

  2. Immediate world reconciliation

    When a season changes, the whole loaded world is updated at once instead of waiting for random ticks to slowly change blocks.

  3. Per-chunk snow coverage map

    The server maintains a snow coverage record for every explored chunk and sends that record to each connected client.

  4. Seasonal LOD coverage

    With Distant Horizons, the coverage map gives distant terrain full seasonal snow coverage.

Questions

Does Season Cache need Serene Seasons?

Yes. Serene Seasons is a required dependency, along with Fabric API. Season Cache changes how Serene Seasons snow is applied, so it has no effect without it.

Does a dedicated server need the mod installed?

Yes, the server side is required for the coverage map. Players who only want the snow changes can join the server with the mod installed on their client as well.

Can it run without Distant Horizons?

Yes. Distant Horizons is optional. Without it, Season Cache still syncs snow and ice in the loaded world, but distant LOD snow coverage is not shown.
