I mean, wow, what you are able to output in a day is really amazing @wlbragg. Thank you! To confirm the gap fixes, yes they all look cleaned up. Just be advised that this -compositor build does not have livery interior fix implemented.
Also, the sounds are a
massive improvement, and we would just need like you said, the RPMs, acceleration/deceleration. This is a really large step in the right direction for sure. I have to agree with you on the quality of the sound clips I provided, not that great after all. I should also mention the Cabin Defrost button tooltip still reads "Cabin Heat":
Cabin Defrost tooltip: Cabin Heat.
Another extremely minor "bug" is from within the Livery Menu, the Low Res liveries are not uniformly named Low Res, some are named Lo Res. Super minor stuff obviously.
Excellent work on everything, the audio is really impressive!
