Just be aware that the linked branch doesn’t render FleX fluids atm, just porting that to 4.23 would still have that same limitation. Can’t give any estimates on 4.23 from my end atm for reasons mentioned above messages.
The main right now is the 4.22+ changes on the rendering side. It may or may not be complicated but my current iteration times are just unbearable with these engine versions so holding off all bigger changes until I get things running smoothly again. And even then, there’s no promises that these are something I can fix but at least iteration times will be bearable again. Of course anyone who’s up for the challenge can still pick these up and try to solve the issues on their own (and hopefully share ).
