The Multilight™ tab has an Emixer, where you can adjust the intensity of the lights and the
ISO and shutter speed. Each emitter in the scene is represented by a slider with the name
of the emitter, including the Sky (any of the available Sky options) and IBL environment.
The Emixer key-framed sequence can also be saved as an .emixer le. This is useful if you
have several camera views of the same scene and you want to apply the same lighting
conditions to other camera views.
• Light Slider: Controls the intensity of the light. It has an input where the exact
intensity can be specied. Next to the input is the current unit of the emitter (Watts,
Lumens, etc.)
• S: Solo button, will set the selected light as the only visible light, dimming all the
others. Please remember that the Solo buttons work like the sliders of an audio
sequencer. For example, if you have 20 lights in the scene, you can choose to Solo
two lights. This is easier than having to mute 18 lights if you only wish to see the
inuence of two of the lights.
• M: Stands for “mute” and will switch off the current light source.
• Color chip: In Color Multilight mode, a color chip will appear underneath the slider
allowing you to change the color of the emitter.
• Max Frames: Maximum number of frames in the Emixer timeline.

• Load Emixer data: Load an emixer sequence le in .emixer format.
• Save Emixer data: Save an emixer sequence le in .emixer format.
• Save sequence: Save a sequence of images which can then be made into a video

u Note: The .emixer le is an ascii format that you can directly open with any text editor to
read and/or edit it, allowing you to easily change the intensity and color of each emitter at
each frame, to adjust the lights animation to your needs.
