What size are the mdl files and how are fps? Too many problems with Carenado aircraft to want to try this on blind faith.
Thanks for checking for me! Looks like I am screwed with them as well as Carenado. Oh well.Aircraft model file size is over 50mb, but the cockpit mdl are over 100mb.
You probably have FSX version installed? I have p3d v4, my interior models are all over 100mbtheseare the file sizes as shown in the model folder
c421.MDL 53364KB
c421_interior.MDL 53159KB
c421_interiorx64.MDL 110577KB
standard interior model is set to c421_interior.mdl

I call BS in reference about painting these releases, theres 1000s of paints for recent Carenado and Alabeo models
if anything they are 100 times easier to paint now than 3 plus years ago
