that was poorly worded, sorry. "I have already put it in place in my development work, so as to be part of a future update for V12" It is not in place in the currently available version.
With X-Plane's RC4, released today, I think X-Plane is in a good place to resume Moo tweaks. I'll probably release updates in two stages.
1) Visual changes, i.e. the rain effects and tweaked lighting...which just looks nicer.
2) Flight model refinement.
I separate out the flight model refinement because it performs reasonably well in XP12 and most users, (me included) enjoy the more visual and sensory aspects of simming rather than 'by the numbers', i.e "we put in gas....we fly....make sure no needled go red, and enjoy the ride"
Chasing numbers always involves more in depth tweaks, longer testing period, and frustrations fighting X-Plane's default models and I don't want to withold some of the cooler XP12 visual features while flight testing/refinement takes place.
