A more complex effect: the Rendering > Lighting effect

This effect is used to light up the image or sequence of your choice as if using an exterior light source (light, projector…).

By default, nothing is present in the list. The Lights menu may be used to create one or several lighting effects among the following categories: Spot, Omni and Ambient.
As soon as a lighting effect is created, you may duplicate, delete or rename it.

The Lights menu displays the name of the light whose parameters are shown in the stack. If you work with several lights you may go from one to the other by selecting their names in the Lights menu.

Here an overview of the different lighting types:

* Ambient lighting lights up the scene globally in the color of your choice. Values under 100% will darken the image, values higher than 100% will brighten it.

* Omni lighting lights up a circular area of your choice similar to a projector located on an axis perpendicular to the image. The parameters to be set are color, lighting intensity, center and radius of the circular area, as well as altitude of the virtual projector.

* Spot lighting lights up the image similar to a tilted projector. Two position parameters are available for this mode, which allow you to adjust the position of the light source as well as its direction.

For many of the parameters described above, the settings may be made directly on the screen (don't forget to display the HUD).

Spot and Omni lighting have a profile editor which works similarly to that of the drawing tools (see lesson 2 for more details).


With the Light popup menu it is possible to use several light sources (regardless of type), as well as to Rename, Duplicate or Delete them.

This is how our cave may be lit up in various ways !

This Lighting effect only applies to the opaque pixels of the current layer. To obtain the examples above it is therefore necessary to first merge the layers of our project.
