## Important **Back up your existing worlds before updating.** This update will most likely break them. ## Overture Maps Integration Added optional **Overture Maps** streets, buildings, and water, which mostly use **OpenStreetMap** data. This feature is still in **early development**, so more improvements, bug fixes, and customization options are planned over time. Coverage is **worldwide**, but some areas may still have issues. Current Overture Maps features include: - Roads with lamps and night lighting - Building decoration - Very basic interiors - Bridges with pillars - Some 3D buildings ### Notes - Buildings currently render only at **1:1 to 1:15** scales - Interiors currently render only at **1:1** scale - Some 3D landmarks may look inaccurate in places (for example, the Eiffel Tower), as this reflects how they currently render in Overture Maps ## Terrain Preview - Terrain preview now shows **3D trees and buildings** - This can be disabled - Added a new **Info screen** in terrain preview showing: - Which DEM is being used in the selected area - Highest altitude in the preview area - Min Y and Max Y values - Warnings in red when Y limits are exceeded - Added an **Auto Adjust** button for players who want terrain settings as close to **1:1 scale** as possible for the selected area ## Cache Improvements - Added full **world-config cache coverage** - Fixed cache clearing so it now removes both **stored** and **runtime** data - Improved cache size totals to more accurately reflect **all Tellus cache types** ## Elevation / DEM Updates ### New DEM Sources - Added **Copernicus DEM** as a new elevation source - Added **USGS DEM**, allowing **1–2m resolution** where available in the USA - Added **swissALTI3D**, providing **1–2m resolution** across most of Switzerland - Added **CANElevation**, adding **2m elevation data** where available in Canada - Added **Japan GSI DEM**, supporting **1m, 5m, and 10m** resolution where available ### Automatic DEM Selection Added **Automatic DEM selection**, which keeps the highest available resolution from: - Terrain Tiles - ArcticDEM - REMA - Other DEM sources where available It uses **Copernicus** in lower-resolution areas. ### DEM Controls - DEM sources can now be **enabled or disabled individually** ### Terrain Quality Improvements - Improved mountains and terrain detail in regions that previously relied on coarse **90m+** elevation data - Fixed poor terrain data in many areas, including places like **Cyprus**, thanks to **Copernicus** ### Antarctica - Antarctica now has **2m resolution** thanks to **REMA** - **ESA WorldCover** has no Antarctica data, so all terrain there currently renders as snow ### Work in Progress: High Mountain Asia DEM Work is underway to add **High Mountain Asia 8m DEM**, including **Mount Everest**. #### Notes - This source requires users to create an account and obtain a token - The token can then be used in-game to access the data - This DEM currently has some locations with **significant missing data**, which can cause noticeable terrain artifacts, especially around **K2** and **Mount Everest** - Tellus will fall back to **Copernicus** where data is missing and apply smoothing to reduce artifacts - This feature is still **work in progress** and is **not enabled yet** ## UI Changes - Increased the maximum zoom available in **Set Spawnpoint** ## Reworked / Disabled Features - Reworking **Historic Snow Coverage** - This option is currently **disabled** ## Fixes and Improvements - Various UI adjustments - Bug fixes - General improvements ## Known Issues - Chunk performance may be poor with some DEMs and in certain areas, especially for full chunks around the player - Some bridges may extend beyond their real-world length - Some coastlines may not render properly with OSM water ## Next Update The next update will focus on: - **Minecraft 26.x** - **Minecraft 1.21.1** - **NeoForge support** on both versions - Bug fixes and optimizations For **26.x**, I'm mainly waiting on **Distant Horizons** to release its update as well.
