Thank you!
I dont remember panda exporter but isnt there an option to choose: Make Y up, or something similar? If yes then no need to rotate your model 90 degrees.
Also, a few tips for better armor protecting and less buggs, The hull for example. Should be totally clean, remove all lights, skirts, toolboxes and so on. Same on the turret. Later on you add them as removable parts that got shoot off when hit anyway
A good way is to remove all details and decorations, add them as a new object and call them for example d_decoration and d_head_decoration.
But you seem to have understand the concept and hierarchy for the game! I have high hopes for this
Good luck!
Ps, im thinking of getting back to mod sabow aswell Ds.
