Hi everyone!
Ok, I just attached a new zip file for the Blender2FSX tool set to this thread. (See first post) I have found a problem with Blender 2.77a when it installs add-ons for the first time. It will not create a "Compiled Python File" for more than on module in a add-on when the add-on is fist installed. So if you have used Blender2FSX before you will have no problem installing it with the zip file. But if you are installing Blender2FSX for the fist time. You will need to follow the these steps.
1. Start Blender then click on the "File" tab.
2. Next click on the "User Preferences" (See Image 1)
3. Now Click on "Add-Ons" tab. And then under "Supported Level" click "Testing" tab.(See Image 2)
4. Next at the bottom of the "User Preferences" page click on "Install From File" tab.(See Image 3)
5. Now navigate to where you have your Blender2FSX .zip file and select it.
6. Next click on "Install From File" tab. (See Image 4)
7. Now in the "User Preferences" Page you will see one module of the Blender2FSX add-on "FSX Materials. Click on it to check it. (See page 5)
8. Next click on the "Save User Settings" button and then close the "User Preferences Page"
9. Close Blender.
10. Now re-start blender and go to "User Prefernces", add-on tab page again. Follow steps 1, 2, and 3.
11. You should see now 3 modules in the the window but only FSX Materials is checked. (See Page 6)
12. Click and check the other 2 modules and then click on "Save User Settings".
13. Close the "User Preferences" window and close and re-start Blender. You are now ready to go.
Thanks, Kris
