:) Question..After installing one of the "World of AI" packages..do I need to decompile that package and then recompile using TTools?
Having just started using WOAI I found that it puts a compiled traffic.bgl file inside your main Scenery>World folder in FS (e.g., installing everything automatically), for EACH package being installed. If you want to use it as is, then there is no need to decompile/compile, as it's already done for you. This is also handy in case you wish to deactivate a specific package, e.g., by simply deleting or renaming the required file(s), although it's probably better to use the uninstaller mentioned above. If like me, you want to mess around with editing the flightplans/aircraft that are provided in the package, then you would need to decompile/compile using TTools. Hope this makes sense.
