.RBXM File Extension

An RBXM file contains a 3D model created by Roblox Studio, an IDE for the online multiplayer Roblox game. It stores a game object, such as a shirt, pants, hat, building, vehicle, stairs, animal, or plant. RBXM files may also contain .LUA scripts used to create content with Roblox Studio.

You can open an RBXM file with Roblox Studio by dragging and dropping the file onto the 3D canvas in the program. You can also right-click the Explorer menu in Roblox Studio, select Insert From File, then choose the RBXM file to import it.

NOTE: Roblox Studio is utilized by users of all levels to create content that can be distributed and used in Roblox, which is an online game platform where people can design their own creative games.
