Hello everybody! This is a problem I bothered me, I use 3Dmax to create a rectangle to add extrusion after I converted into babylon format file, when I load the program I found how its axis can not be changed, Even if I center it in 3Dmax, it still does not solve the problem, its axis is always on the side and can not be centered; I do not know if you have not encountered this problem, the only way I can think of is to change the model to another way Re-do, what better way to solve ........! thank you very much! ! !
