Game maker 3D Scene editor and sample game

Game maker is primarly focused on 2D games; but it has 3D functions,

unfortunately, there is no tools to edit 3D Room.  There is a solution i am building for you: a 3D scene editor.

You can import .obj files, aswell as textures files, and assign textures to the object. 
you can also move and rotate the objects in the scene using the mouse (on the x and y axis, simply drag the object to the desired location, then use the ctrl while moving to move it in the Z axis)

use left shift when you click to an object to duplicate it.

You can export the project to your disk, it will export a text file, with the list of objects added to the scene, and export the .obj to game maker buffer for fast loading.

then you can import the project to the "included files" of your game maker project 

the sample game show you how to use the exported scene in your 3D game. the camera is setup as 3rd person view, you can use the mouse to move the camera around the player, and use the arrow key to move the player.

A sample characters with all animations is included in the project (in the included files, it there is a zip fille with 800 frames for the different animations)

the graphics assets are provided for demo only, you can not use them for the game you distribute
