If you get to a point where you can not fix your problems, then you have the option to send me your Blender file. But I would suggest first try to export an object at a time and that will let you know where your problem is. Did you try to fist export a simple cube. And see if you can get that into FSX? The best thing to do is to start small and then work your way up.Well wadda ya know. Cleaning up to conform to the naming convention at least got the model to compile. I'll plug away from here.
Kris, I am perfectly OK sharing my files with you. If you feel it is best to help me along offline, I am OK with that.
The best practice that I have found when it comes to working on a project for FSX. Is to not wait until you have the whole project done before you try to export it and get it into FSX. Model and export as you go. That way you will save a lot of time trouble shooting.
