## Geometry

### Normals

Parameter ID: `GLTFIMPORTER_NORMALS`

Here you can define how Cinema 4D will handle any existing Normals in the file:

- **None**: No Normal information is imported. Objects appear faceted.
- **Vertex**: Vertex Normals will be imported using a Vertex tag.
- **Phong**: Each geometry object will contain a Phong tag.

### Phong Angle

Parameter ID: `GLTFIMPORTER_PHONGANGLE` · Range: [0..180°]

Define a Phong angle here. This defines the angle up to which the shading between two neighboring surfaces should be smoothed (see also [Phong Angle](https://help.maxon.net/c4d/en-us/Content/html/TPHONG-ID_TAGPROPERTIES.html.md)).

### Vertex Colors

Parameter ID: `GLTFIMPORTER_VERTEXCOLORS`

If this option is enabled, vertex colors contained in the glTF file are imported as [Vertex Color tag](https://help.maxon.net/c4d/en-us/Content/html/TVERTEXCOLOR.html.md).

### UVs

Parameter ID: `GLTFIMPORTER_UVS`

Activate this option if UVW coordinates should be imported in the form of a UVW tag.

### Flip Z

Parameter ID: `GLTFIMPORTER_FLIPZ`

Normally, this option should be enabled, then the scene will look the same in Cinema 4D as it does in external programs.

For the different coordinate systems, glTF uses the right-hand rule (Z-axis points forward), while Cinema 4D uses the left-hand rule (Z-axis points backward).

The practical difference is the mirroring of the objects with respect to the Z axis.

### Split Meshes

Parameter ID: `GLTFIMPORTER_GEOMETRY_SPLIT_MESHPRIMS`

Activate this option if polygon islands should be loaded as separate objects, otherwise all polygon islands of an object will also be placed in just one object.
