A combination of C++-written mesh voxelizer and a Bukkit server plugin which allows to build .OBJ models in Minecraft.

You need a Bukkit server running on some UNIX. Then go download the latest release and unzip it to your <server_directory>/plugins as is.

Create a directory named 3dmodels in the server root and store your .obj models there (models must be triangulated!).

You must be logged as a player on a Minecraft server.

Command: '/build3dmodel <modelname> <dimension> [material], [material], ...'

Example: '/build3dmodel suzanne.obj 128 STONE, GRASS_BLOCK'

You can specify as much materials as your .obj has, in the same order as your modeling software exports. No .mtl needed/supported, you supposed to specify minecraft blocks which look similar to your materials by hand.

• Minecraft client leaves the server while long-time building due to tick timeout.
• Also server itself can crash due to default timeout (60 sec). You can override the timeout in the server properties (set it to -1 to turn it off).
• If building process continues without player on a server, the lighting on the blocks will be broken. For now, you can fix the lighting after building completed using some another bukkit plugin (e.g. LightCleaner)
