Controlling two ESP32 microcontrollers via Resolume

[Ricky]

I would like to control 16 led strips over Artnet with Resolume Arena 6 but am struggling to make the connection between Resolume and the hardware. Here is what I got so far:
My controllers: 2 x QuinLED-Dig-Octa System Brainboard (some fancy board for an ESP32 with LAN port, easy power supply etc)
16 x WS2815 strips, each 4.5m with 60led/m which gives me 270 leds per strip, which makes 4320 LEDs
Every strip has an individual data input, each ESP32 gets 8 inputs.
The strips are arranged in one big matrix (5x8m if that’s of interest)
My knowledge concerning DMX:
One DMX universe can only fit 170 leds, so I would create two universes per strip.
There are only 16 universes available but there are also 16 subnets each with 16 universes.
DMX wise I should be able to fit all my LEDs into 2 subnets that each have 16 universes.

In Resolume I would create two lumiverses (one lumiverse is basically a DMX universe, right?) for one led strip and assign it to the corresponding universe/subnet. For example:
Strip1_half1: Universe0, subnet0
Strip1_half2: Universe1, subnet0
Strip2_half1: Universe2, subnet0
Strip2_half2: Universe3, subnet0
…
Strip9_half1: Universe0, subnet1
Strip9_half2: Universe1, subnet1
Etc.. So far so good.
Questions:
1. How do I assign 2 lumiverses to one output pin on the ESP32? And how would I assign the next two lumiverses to another output pin?
For example like this: lumiverse 1 and 2 go to pin 2, lumiverse 3 and 4 go to in 3 and so on?
2. How does that work with subnets?
I found this example sketch: https://learn.sparkfun.com/tutorials/us ... pixels/all
but it just uses one output pin and one subnet which still leaves my questions unanswered. There is also an official guide by resolume but it uses a SPI bus so that isn’t of much help either.
I don’t really mind if I’ll end up using WLED or FastLED or something else.

The pixel controller probably has a web interface where you can set this up

2. How does that work with subnets?

Subnet:Universe is just a logical division, so people can deal with the numbers better, saying S3:U2 instead of universe 50.
Each subnet can have 16 universes.
