# Animation inside a .obj file?

Ok, so yesterday I understood that "rigging (bone and joints)" are things that are use inside a 3D animation software like maya. By that I mean that those bones and joints are not inside the .obj file but only inside the software to help you animate the model.

My plan was to create my own voxel model using my own editor, then load it up into maya to animate it and then put it inside Unity to use the animation but from what I understand, its impossible to put multiple frame inside a file to use the pre-made animation inside a software like Unity.

Does that mean that I will have to load my voxel model inside unity and animate it using the Unity Animation Engine ?

• Alternatively, dae and fbx are the most commonly supported, industry-standard model formats which include animation data. You can use any program which is capable of exporting to those formats to do the rigging (Maya, 3DS Max, Blender, Modo, etc.). Most of these support md5 as well. – Dan Jun 7 '16 at 18:01
