Hello, I had the same goal as you a few months ago and put a lot of time into it.
The way I am doing it now is using MA dot2 for DMX input and to control the lights. You can also timecode a show in there. Which you can record in unreal and save as a sequence. I recommend looking into the DMX previs sample It has some great fixtures and settings.
You can find more info about it here: https://docs.unrealengine.com/5.0/en-US/dmx-previs-sample-project-for-unreal-engine/
They provide a MA grandma2 project file which includes the correct fixtures for them. However you don’t get a free output universe like you do with DOT2. So what I did is export the fixtures out of grandma2 into the ma fixture builder. Export them again into dot2 and you are able to use them with unreal.
If you are really interested i’m willing to give a more in depth explanation about how to set everything up but see if you can figure it out yourself first.
