No problem, I'll potter along with the Gazelle animations. If you want, you can use it for FGUK when I'm done.
The EC120 is looking good and I presume you also got the paint kit for it. I found the most difficult part was the VEMD - particularly the torque calculations. Let me know if you need anything extra for it.
Just in case of confusion for anyone reading this in times to come: MP does NOT transmit the actual livery/graphics file to the other MP players. It simply transmits a location/file combo such as
The receiving MP player's system will (if possible) load this file from its OWN system and apply it to its OWN current aircraft/fuselage model
The transmitter/receiver MP players do NOT have to have the same aircraft/fuselage models or the same livery/graphics files. So I can use this new version over MP and users of the older version will simply see the old model with the old livery.
The theory that smaller (.jpg) files load faster (over multiplayer or anywhere) is also debatable. One reason they are smaller is that they contain less information. For sure, your machine could transfer them to your graphics card faster but they are of no use as they are - they have to be decompressed. The graphics card needs them in a pixel-by-pixel format so it has to spend time creating this and ending up with an inferior product than if you had just sent it in .png format in the first place. Yes, .dds format graphics may be ideal but they are very difficult to work with.
Using a higher resolution JPG (which has lossy compression) usually gives better rendering than a lower resolution PNG (which can often still be larger on disk). So I'd recommend a higher resolution JPG.
Secondly I've just realised that the DDS texture cache without compression may actually be a valid use case as it seems that DDS with compression (nvtt) is only working reliably on Windows.
The DDS texture cache is definitely worth leaving turned because it removes most of the frame pauses related to model loading; unless you are getting specific problems with it (please report all problems to the devlist or the main FG issue tracker)
