The scene effects are designed to enhance the 3D compositing environment.
Environment Map Transform
Can be used on a wraparound environment map to adjust its position without losing its wraparound appearance.
Applying this to an ordinary layer will create unusual results.
Environment map viewer
This wraps the selected layer onto a spherical shape.
When placed as the bottom layer in a 3D composite shot, this creates a convincing, wrap-around background for 3D shots.
Examples would be a sky background for a cityscape or plane shot, or a space nebula for a spaceship fly-by.
The environment map viewer will automatically update as the camera is panned in all directions.
The parallax effect creates the illusion of 3D depth in a 2D layer.
In this example parallax has been used to apply a cracked concrete texture to some text:
The height map is used to determine the depth effect.
When set to None the host layer's own texture will be used for the parallax effect. You can also choose a different layer to use as the height map.
The Blur Height Map property can be used to create a softer, smoother parallax effect.
The parallax effect is most effective when combined with HitFilm's 3D lights.
