Most 172 liveries should work on the JTA with just a little massaging.
-
Edit the aircraft.cfg file and change
base_container = "..\Asobo_C172sp_AS1000"
to
base_container = "..\C172TDI"
-
Edit the texture.cfg file which should look something like this.
fallback.1=…\texture
fallback.2=…\texture\Gauges
fallback.3=…\texture\AS1000
fallback.4=…\texture\detailMap
fallback.5=…\texture\Glass
fallback.6=…\Asobo_C172sp_AS1000
fallback.7=…\texture\Planes_GenericLayouts of each livery’s texture.cfg may differ slightly but the important thing to remember is to add the additional line BEFORE the Asobo_C172sp_AS1000 line to point to the JTA folder texture folder, then renumber the lines so they are sequential. In the example below I have added a new fallback 6 line and renumbered the old fallback 6 & 7 lines to 7 & 8.
fallback.1=…\texture
fallback.2=…\texture\Gauges
fallback.3=…\texture\AS1000
fallback.4=…\texture\detailMap
fallback.5=…\texture\Glass
fallback.6=…\C172TDI\texture
fallback.7=…\Asobo_C172sp_AS1000
fallback.8=…\texture\Planes_Generic
Or you could save yourself some work as my 172 liveries are already set up for the JTA.
