Advanced properties

The advanced panel contains additional controls for defining how the model behaves in HitFilm.

After adjusting the advanced settings the Update Preview button must be clicked to see the changes in the preview.

Coordinate system

Flip YZ axis can be used to alter the default orientation of the model. This is useful if the model has been built in software that uses a different coordinate system to HitFilm.

Center anchor point will ensure the anchor point is at the center of the model. This can be useful if the model is offset in 3D space.

The coordinate system can only be adjusted during import.

3D model units/scale

The scale of an imported model has to be adapted to the HitFilm 3D scene.

Auto normalize will scale the model automatically to fit within a cube 500 units on a side. This will ensure the model fits neatly within the frame of a default HitFilm camera.

If you are working with multiple models or multi-file models that have been created to a specific scale you should uncheck auto normalize and set the Single Unit Scale. This will ensure all models use the same scale.

The unit scale can be set using the drop-down menu and the value set with the slider.

The scale of a model directly affects the behaviour of ambient occlusion. Small scales will produce deeper ambient occlusion, creating the impression of a smaller model.

The model scale can only be adjusted during import.


In most cases the Normals properties should not be changed. Only alter them if the model is rendering incorrectly.

Normals are used to determine how light interacts with a surface.

In the event of lighting seeming inaccurate, with areas appearing dark when they should be light, activate the Flip Normals property.

The Generation Method can be used to create normals for models that do not have them, or to alter the existing normals. Auto smoothing creates a more realistic surface, while faceted produces a surface that highlights each individual polygon.

UV mapping

UV mapping determines how textures are applied to a surface. If textures are appearing inverted or upside-down, make sure you activate the Flip UV Coordinates property.
