Thanks Gil! That's done. I was just wondering when I went to setup in xlights and right clicked on my p5 network e1.31 input it had an FPP option to send it to. When I right clicked and went to send to output it had a FPP cap option to send it too. Just curious.
xLights doesn't (currently) know anything about the panel setups. Thus, it cannot do any setups for FPP related to that. However, xLights DOES know about and can configure certain things for FPP which is what those popups are for. Mostly, this includes:
1) e1.31/Artnet/DDP outputs - if you use FPP as a master to output to other controllers, this will copy all the outputs from xLights to that FPP instance and setup all the universes and everything.
2) e1.31/Artnet inputs - when used for bridging, this will setup the universes and channel ranges and such to listen on.
3) Pi/BBB ws2811 hat/capes. (PiHat, F#-B, etc...) If you have outputs configured on your models, xLights can setup the string outputs
All of that is for FPP v2.0. v1.x is limitted to #1 above I think.
