Doom Builder 64 Enhanced

What Doom Builder 64 Enhanced is

Doom Builder 64 Enhanced is a free Windows map editor forked from Doom Builder 64, with the stated aim of updating its source code and adding tools for mappers. It supports DOOM 64 Remastered, DOOM 64 EX+, DOOM 64 EX+ Enhanced, and DOOM 64 N64 engines, as well as 2D and 3D level dimensions and entity placement. Plugins include a Comments Panel, Copy Paste Sector Props, Stair Sector Builder, Statistics, Tag Range, and Reject Editor. The Reject Editor may crash when first saving a new map that has no WAD file of its own; the project says it works after loading and saving a map with an existing WAD. Updating the code to the latest original Doom Builder 2 source remains in progress. The project distributes binaries as a ZIP from Releases; users extract it and launch Builder.exe rather than using a traditional installer. Microsoft .NET Framework 3.5 is required, and only building on Windows is tested and officially supported. The repository lists GPL-3.0 licensing and release versions 1.0.0.1 and 1.0.0.0.
