If you have lets say 4 busses:
B-V 1001
B-V 1002
B-V 1003
B-V 1004
then you need 4 separate exterior textures just because of the plates. Why not just paint the plate netral and use a text texture like in almost 95% of OMSI busses? Then you would just need one repaint for X busses. I can mod that for myself, but thats something every bus should be able to deal with, and the very most do well.
Heatimg:
sorry, no it does not work. I tried that in the Voith and ZF versions, with AC and no AC. It does not matter if you press the AC/heating button, heat is only applied if you turn the vent to something > 0. No matter if you press the button or not. What works is the temperature presets: the temp will not be higher than that.
The normal behaviour should be that turning the vent even to 100% should have no effect on temperature as long as you don't press the heater / AC button. But it's heating anyway, it just has to be something above 0.
As for the speed of heating: it's not always fast. It's turbo-heating when the engine has run for a while. There seems to be a very high dependency between engine temp and heating, which is good but much too high.

ANSI/UTF8:
If you do not change it to ANSI any german and probably some other countries characters will be not displayed correctly. If you want to try it just load a bus with the TH-Wald hof and select destination 2 "Müller Touristik". you get something like "M?ller Touristik". When you convert the otf files it will work. The scripts will also have bugs because of that, OMSI just can't deal with UTF coding.
AI-busses:
Unfortunetly I can't use the 7700A as AI bus. As AI bus the bus opens the front door and then some kind of a loop starts (you hear a noise loop from the bus) and the bus won't move anymore.
