The FX files are just meant to enhance the visual. All the other files remain as originaly released.
In summary the FX added wakes, foam, correction to sub characteristics, sensors positioning etc. Just few work hours have been put, thats why is still a work in progress since there are alot of other things too look at.
The 3D needing a bit of rework at tower and rudder to be similar to real Typhoons; paint job; the directory structure needing a change to avoid clashing with other subs; removal the "remains of source sub"; add wake layers are just few of many other things to look.
If I'm not wrong the radar is hidden on the tower since the game doesn't allow to control it
Once I get the Ohio's compartments out I'll dedicate more time to Typhoon to get more stuf done
