SourceCraft is a unique tool that allows you to play Minecraft using the Source Engine. The Source Engine is used to run popular games like Team Fortress 2 and Counter-Strike: Source.
How does SourceCraft do this? Well, it simply converts Minecraft files into vmf files. Vmf files can be opened by the Hammer Editor, which is used to edit files for the Source Engine.
Once the Minecraft world has been converted into a vmf file, players can edit it and play it inside popular games like Counter-Strike or Team Fortress 2. Team Fortress 2 is available for free through Steam
There is one limitation to SourceCraft – it won’t convert maps that are larger than 8900 cuboids. If players try to convert maps larger than that, it will automatically reduce that amount. In other words, SourceCraft cannot be used to render endless block worlds.
Otherwise, SourceCraft allows players to navigate their world using the familiar interface of Counter-Strike: Source or Team Fortress 2. For some players, this will be a perfect blend their two favorite games.
