Hammer++ vs Remere's Map Editor

Hammer++ is a free Windows modification of Valve’s Hammer editor for creating maps in the Source engine. It aims to improve stability and keep the editor current through fixes and changes. It can simulate Source lighting inside the editor, with adjustable quality and speed and dynamic updates, and preview particles, fog, skyboxes, rope physics, render effects, and material proxies. Mapping tools include a 3D gizmo, polygon and sprinkle tools, multiple cordons, brush merging, and object placement on floors or ceilings. If the editor crashes, it shows a detailed error message and autosaves open VMF files. Saved VMFs retain precise vertex data while also storing less precise data for compilers and compatibility with other Hammer versions. Downloads bundle HLMV++, which can be installed optionally. The download page lists build 8871, last updated April 14, 2026. The maker directs users to its official Discord for discussion and says the project is not affiliated with Valve. It also notes antivirus software sometimes flags downloads and advises allowing them or adding an exception. The old Source 2013 Multiplayer version is unsupported, and CS:GO support is frozen on build 8864.

Remere's Map Editor is a free map editor for OpenTibia, an open-source implementation of the MMORPG Tibia. It provides tools for creating and managing maps, including tile and entity placement, terrain flood fill, waypoint tools, and animation previews. Search tools can locate items and find unique IDs, action IDs, containers, and writable items in a selected area. Users can import and export zones and export a minimap for a selected area. Version 4.0 adds compatibility with the Canary and Assets Clients repositories, reads assets from client 11 or higher, and includes Lua scripting and a real-time monitor for FPS, CPU, and RAM. The project supports Windows, Linux, and macOS and provides compilation guidance for each; compiling requires wxWidgets 3.0 or later and Boost 1.55.0 or later. The project is licensed under GPLv2. Its README points to the official website for releases and provides a separate download link for version 3.X until it is added to that site. The free plan costs nothing; redistribution is allowed only in unmodified form.
