* raylib [models] example - loading gltf
|
||||
*
|
||||
* This example has been created using raylib 3.5 (www.raylib.com)
|
||||
* This example has been created using raylib 4.2 (www.raylib.com)
|
||||
* raylib is licensed under an unmodified zlib/libpng license (View raylib.h for details)
|
||||
*
|
||||
* 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.
|
||||
* Also make sure the scale parameter of your models is set to 0.0,
|
||||
* scaling can be applied from the export menu.
