Well. i forgot notice this, these import parameters i saw just with ? marks, i made some experiments, but probbably miss some important. Using IMDeditor is innercial, because i had nothing else and because "the manner is an iron shirt".
As i wrote, i have no experience with 3dsmax. Whole matter with addon is for me just about creating spheres for new/changed shapes of ships, look into original ships i can make good enough with IMDeditor (despite of mixed Y/Z axes)+ blender.
Enough talking, thanks you much, must go testing, give feedback.
