Chunkmap vs MCA Saenk

Chunkmap generates top-down 2D maps of Minecraft worlds from region (.mca) files. Its web viewer lets users upload their own region files, and it covers the Overworld, Nether, and End. The Windows CLI can render individual region files or combine rendered images into a single map. Its rendering modes include textures, heightmap, biomes, temperature, downfall, and inhabited views. The CLI is open source under the MIT license on GitHub, and the product is free. Chunkmap supports offline viewing and links to a Discord community. The project is labeled beta and under development, so it may not work as expected. The beta has only been tested with Minecraft 1.21.x worlds; modded worlds and chunks generated before 1.18 are unsupported. The project README also notes that Nether generation is slower than generation for the Overworld and End. The web version is for uploading and viewing region files, while the CLI provides rendering and map-merging options.

MCA Saenk is a Windows top-down rendering mapper for Minecraft that produces screenshots and can export them as in-game maps. It renders 3D shading from multiple angles and can reproduce the look of in-game maps when settings are calibrated. Styles include default, Java map, Bedrock map, and betaplus, with custom styles possible from resource packs and mods. The tool handles semi-transparent blocks, filtering, and custom blocks, biomes, and dimensions from mods and datapacks. More than 30 settings cover contrast, lighting, shading, colormaps, biome blending, and water translucency, with many adjustments using hardware acceleration. A virtual screenshot window can be dragged and scaled before capture. Official Java releases from 1.2.1 through 26.2 are supported, while Fabric and Forge modded-world support is an aim. OpenGL rendering requires version 4.0 and falls back to legacy rendering when unavailable.
