I've been playing around with new installs of CFS2.
I was curious to understand why in my original I could go as high as 100-99 planes, yet in my last most recent install I could only have 59.
I originally backed up all of my modified folders, (aircraft, GSL, textures, and scenerydb) and what I had done was simply dump all the fines in to CFS2 at once. This was the wrong thing to do, as it resulted in a reduced active plane library.
I have done some reading on the web, and in these forums and its generally accepted that the 100 plane limit is a function of the CFS2 engine (specifically the mission building). But there seems to be vagueness as to what really causes the limitation. Some believe it is a combination of the number of aircraft, ships, and objects. Others state its only dealing with the number of ships and planes, and I have also read examples in dealing with the number of scenery.cfg items and planes.
So I went back through and did a systematic install. First (after installing and running CFS2 stock once) all of the planes I have (424) were installed and then I installed ACman and reduced the number of active aircraft to 100. I then started CFS2 and tried to do FF with stock scenery, objectsdp, and ships. I received the classic 100 plane limit error, and thus reduced the plane count to 99. Started CFS2 again and was able to get it to work.
After that I installed the effects, objectsDB folders then in the scenerydb I installed the INF, VEH folders. I then went in to CFS2 and loaded FF agian with 99 planes.
I continued this process through installing the world texture then Rhumba's meshes, world objects and then fields.
so far I can have 99 planes active and the only folder I have not modified yet is the GSL folder.
So I am wondering, could the GSL folder in a complex CFS2 install have the effect of reducing the active plane library capacity from 99 to 59? Perhaps in the event if a complex CFS2 file was introduced without gradually building up the file.
