Really need someone help!
I'm new to working with DMX and tried to follow some examples but still can't figure it out.
What i'm trying to accomplish is to control a DMX light fixture that is setup in UE5.2 and at the same time control a external DMX Moving Head light simultaneously. I'm using Q Light Controller to manage both.
I can switch the universe to control each light but not at the same time. I have in Aximmetry I'm not able to see the DMX Out IP on my network card. I think this could be the issue but I'm not sure. Please see the screenshots below which might help to see what my issue could be.
1. PKnight ArtNet in & Out device (I have a wireless for my DMX out for the external Moving Head light).
2. NetGear Switch that connects the ArtNet DXM to my Network Card (No Router)
3. DMX Out not showing the adapter even after manage device has network card selected.
4. ArtNet selected for DMX Input (I notice that I didn't need to have this module and the light control still works)
5. DMX Device selected
6. Adapter selected
7. DMX Out doesn't show the device!!!
8. UE5 Setup
9. Controller Configuration
10. Q Light Controller software
11. DMX Moving Head light
I hope this help to show what my setup is.
Thanks and advance!!!
Hi Dwayne,
I'm not really an expert in DMX, but I've made some similar tests in the past, with a very similar setup. I also had some headaches back then but got it to work eventually.
First, you're right that you don't need a DMX device if you're only using ArtNet with Unreal : Artnet is already visible on the network.
To make sure everything is being transmitted as it should and debug if need be, I would suggest downloading "Artnetominator", it's a lightweight program monitoring Artnet signal on the network. You'll be able to see what is really broadcast.
It's only useful to have such a device to pilot physical fixtures using DMX cables.
Second, you seem to want to sync an unreal fixture and a physical fixture from the same DMX program (Q Light in this case). If that's the case, you don't need to involve Aximmetry at all in the setup.
You can simply let Q Light broadcast its signal, and patch the Unreal fixture and the physical fixture to the same adress and same universe and they'll do the same thing. Involving Aximmetry in the middle to rebroadcast the DMX signal is only complicating things, unless you have a very specific reason to do it.
Third, I don't know if this is still the case, but I remember pulling my hair out last year or so when testing DMX with unreal. It was all very erratic, working some times, not others, until I realized that it wouldn't respond at all if the DMX signal was "static" (eg : "Full On" all the time). I suppose it's to save bandwith or something similar, but you always had to have at least a small change on the first frame for the DMX signal to be updated and picked up in Unreal. Else it would remain "blank" and nothing would happen.
Hope that helps.
Best,
Eric
