The Cycles 4D Light Manager makes it much easier to manage lights in a Cycles 4D scene.
Here is an example showing the two lights in a scene:
The controls are very straightforward. They are as follows:
1. Checkbox to the left of the window
Uncheck this switch to turn a light off, or check it to turn it on again.
2. Button with the light's name
Click this button to select the light in the object manager.
3. Color field
Click to change the light's colour.
4. Light type menu
Use this menu to change the type of the light - point, area, etc.
This is a multiplier for the light's intensity. Increase it to brighten the light and decrease it to darken the light.
6. Shadows checkbox
If checked, the light will cast shadows; if unchecked, it will not.
