* raylib [models] example - Load 3d model with animations and play them
*
* This example has been created using raylib 2.5 (www.raylib.com)

********************************************************************************************
*
* To export a model from blender, make sure it is not posed, the vertices need to be in the
* same position as they would be in edit mode.
* and that the scale of your models is set to 0. Scaling can be done from the export menu.
