Someone asked this over e-mail
Is Lightact able to communicate with multiple DMX devices and create custom shaped matrixes?
Sure thing.
I would suggest you start by:
- watching a dedicated playlist of YouTube tutorials,
- reading a dedicated chapter in our user guide,
- have a look at the sample projects in the eDMX tab in the Welcome screen when Lightact opens or
- download LightWell sample project from our website.
This should keep you busy for some time 
Also, if you want to integrate DMX devices with Unreal Engine content, you can do that either by sending textures from UE to Lightact using Spout and then mapping them to DMX lights or by sending variables from UE to Lightact and then using ArtNet Channel Setter node
in combination with Channel override setting of an Art-Net node in the Devices window.
If you have any questions though, feel free to ask here.
Thanks,
