LED mapping, also known as pixel mapping, allows you to convert pixels into DMX data. Especially to control LED strips or LED matrixes, but also individual lights or sunstrips.
First, create a
DMX layer by clicking on the
triangle icon in the bottom-left corner :
Note that you can create
DMX layer both in dashboard and timelines.
DMX layer will always be on top of other layers :
Indeed, they use the content of layers below them :
In this case, the DMX layer is converting 8x4 = 32 RGB pixels into DMX data, continuously updating the value of 32x3 = 96 DMX channels.
This can control a 8x4 LED matrix for example.
Please note that
DMX layers can be used in a timeline, and this timeline can be embed in the dashboard as well. But be careful not creating conflicts between DMX layers, if they try to control the same DMX channels.
DMX layers share some properties with other layers, but they also have settings to configure how they send DMX data :
More info about DMX devices can be found in this article : Devices
They also defines a
The color format of your LED (RGB, BGR, mono, …) and the bits (8 or 16).
Note that you can create your own format of fixture, see next section.
Indicate the number of LED for your fixture
Options to obvisouly reverse the order of the LED.
The texture's size from which the LED colors will be compute.
This is often useful to set an arbitrary size to match your content size.
To modulate how DMX data is affected by pixels brightness, see next section.
hamburger icon next to the
fixture field to open the fixture editor :
This is useful if you are using LED with a special format, or if you want to control something else, such as a light.
The second tab of the popup allows you to create
This is useful when your LED do not display the right color/brighness, because colorimetry of LED is not linear.
