OBSIDIAN

OBSIDIAN is a procedural map generator developed as a community effort. It is a of the final version of OBLIGE that has two prominent differences: a new GUI for changing the tool's many settings and fully incorporating the older ObAddon project. The merger of ObAddon provided a large addition of visual assets and Lua code.

First released in March 2021, OBSIDIAN currently has two versions: a stable beta and a rolling preview build of the next beta. The builds for Windows are provided at the GitHub repository, but official Linux builds are not yet provided. The project has clear goals for an eventual 1.0 release.

Features
These features of OBSIDIAN are different from OBLIGE:
 * Customizable GUI
 * More prefabs and shape grammars
 * New method for all modes, based on the xoshiro256 algorithm from fastPRNG, which provides exponentially more potential seeds (2^64-1 versus 2^32-1)
 * Ability to use arbitrary-length strings as RNG seeds
 * UDMF output, with the ability to convert existing binary-formatted prefabs at runtime
 * ZDBSP as the internal node builder, providing compressed, extended, and UDMF-compatible nodes for engines that support them
 * Vanilla Doom support, via the bundled SLUMP generator
 * Optional PK3/ZIP output
 * Ability to save an animated GIF of the map-building process
 * "Surprise Me" total randomization of settings
