 There are number of built-in properties, that Fyrox will try to assign automatically if they're defined
 in your shader:
 
-| Name                       | Type            | Description                                 |

-| fyrox_worldMatrix          | `Matrix4`       | Local-to-world transformation.              |
-| fyrox_worldViewProjection  | `Matrix4`       | Local-to-clip-space transform.              |
-| fyrox_boneMatrices         | `[Matrix4; 60]` | Array of bone matrices.                     |
-| fyrox_useSkeletalAnimation | `Vector3`       | Whether skinned meshes is rendering or not. |
-| fyrox_cameraPosition       | `Vector3`       | Position of the camera.                     |
-| fyrox_usePOM               | `bool`          | Whether to use parallax mapping or not.     |
-| fyrox_lightPosition        | `Vector3`       | Light position.                             |

 To use any of the properties, just define a uniform with an appropriate name:
