Someone who knows and has the necessary knowledge can mix them and get the 4.22 with flex and blast

Do note that 4.22 FleX port doesn’t render fluids as stated :

@windywang

I ported FleX to 4.22 based on 's 4.20 integration, without fluid rendering (too much conflicts): https://github/xoyojank/UnrealEngine/tree/4.22-FleX
