Hi,

There will be no single tutorial that fits all users. Your setup depends greatly on several factors: the hardware you're using (for example, the type of lights and DMX control boards), how you've configured your system, the type of production you're working on, and the version of Unreal Editor for Aximmetry you have installed.

Here are several DMX-related documentation links to help you get started:

1. General description of DMX: https://aximmetry.com/learn/virtual-production-workflow/supported-hardware/controllers/controllers/#dmx-artnet 
   
2. DMX modules within the Flow Editor: https://aximmetry.com/learn/virtual-production-workflow/setting-up-inputs-outputs-for-virtual-production/external-controllers/using-dmx-with-aximmetry/ 
   
3. Pixel mapping via DMX. If you're working with a large number of DMX points, you may need this: https://aximmetry.com/learn/virtual-production-workflow/setting-up-inputs-outputs-for-virtual-production/external-controllers/pixel-mapping-via-dmx/  
4. Sending Data to Unreal Engine (to control lighting within Unreal), refer to this guide: https://aximmetry.com/learn/virtual-production-workflow/obtaining-graphics-and-virtual-assets/creating-content-in-ax-scene-editor/additional-control-with-blueprints  

Anyway, here is a short basic (no Pixel Mapping) step-by-step guide (Aximmetry ↔ Unreal ↔ Real Fixtures):

1. Protocol Check:
   Aximmetry outputs DMX via Art-Net. If your fixtures accept only DMX/XLR, you will need an Art-Net to DMX node (converter). If your setup is sACN-only, a conversion step will be required.
   
   
2. Select the Correct Network Adapter in Aximmetry:
   Go to Aximmetry → Manage Devices →  DMX/ArtNet and select the network interface card and port that Aximmetry should use for Art-Net.
   
   
3. Bring DMX into Aximmetry (Flow Editor):
   Add a DMX Input (for dimmer/intensity control) and/or DMX Color Input (for RGB/optional W).
   Set Device to "ArtNet: Node" (Aximmetry will act as an Art-Net node on your network).
   Patch manually (set Net/Subnet/Universe/Channel) or use the Learn function (move a fader on your DMX console to auto-detect channels).
   For smoother fades, use 16-bit (coarse/fine, endian options) if your hardware supports it.
   
   
4. Expose Unreal Light Controls to Aximmetry (AX Scene Editor):
   In AX Scene Editor → Level Blueprint, add:
   Get Aximmetry Scalar → Unreal light Intensity
   Get Aximmetry Color → Unreal light Color
   
   
5. Connect DMX to Unreal Controls (within Aximmetry):
   Connect Aximmetry DMX outputs to the exposed Unreal Project pins, e.g.:
   DMX Input (0–1) → UnrealProject:KeyIntensity
   DMX Color Input → UnrealProject:KeyColor
   
   
6. Output DMX to Real Fixtures (within Aximmetry):
   Add modules such as DMX Out (single channel), DMX Color Output (RGB/W), or DMX Array Output (blocks of channels).
   Select the target Art-Net node in the Device dropdown.
   By default, Aximmetry outputs values in 0–1, which are converted to 0–255 (8-bit) DMX values. For finer control, enable 16-bit output if your fixtures support it.

If you can provide more information about your situation, I am sure we can assist you further.

Warmest regards,
