MCA Saenk vs Tectonicus

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.

Tectonicus generates a detailed, zoomable map from a Minecraft Java world by building a 3D model and rendering map images. Its stated aim is to make maps resemble what players see in Minecraft. It runs on Linux, macOS, and Windows; maps can be viewed offline or served from a web server. Setup involves downloading a release, preparing an XML configuration file, and running the program from the command line with Java. Later runs using the same options are quicker after the initial render because only changed tiles are rendered. Players can filter which signs appear, and signs marked with #view can create first-person views with configurable height, angle, field of view, and nighttime rendering. Release 2.31 supports Minecraft 1.21 through 1.21.11, but not Minecraft 26.1. It also adds rectangular world subsets and arm64 LWJGL libraries for M-series Macs and possibly other ARM systems. Generated images can consume gigabytes of disk space depending on world size; WebP or JPG output and closestZoomSize can reduce storage use. Copper golem statues do not work, and shelves render only partially.
