+*   Example complexity rating: [★★☆☆] 2/4

+*   Example originally created with raylib 2.5, last time updated with raylib 3.5
+*
+*   Example contributed by Culacant (@culacant) and reviewed by Ramon Santamaria (@raysan5)
+*
+*   Example licensed under an unmodified zlib/libpng license, which is an OSI-certified,

+********************************************************************************************
+*
+*   NOTE: 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 the scale of your models is
+*         set to 0. Scaling can be done from the export menu
