Great Idea Rubini.

I'm going to suggest some things to you so you may use my advice according to your interest should you be interested that is.:hmm:
The exhaust also should spray hot steam after the water level drops. I've seen that in a few photos. I'm hoping you could add that with the smoke exhaust from RB's N-sync with yours.
There are a few mods here that uses Particles too.
examples,
OLC Enviroments mod By Onelifecrisis
Tomi_099 VIIC/41 uses particles with the help of Privateer. There also adding a similar mod idea to a VIIC model. With water draining from the holes.

GWX 2.0 and more.
Are you going to make your mod compatible with those other mods or will yours be standalone mod?
I like to hear your ideas on this great addition to SH3 world.
Thanks
