Hi,
so most of the time that i open 3Dmax file, information window show up with the message (its either that the license is going to expire soon, or some parts of the model is hiden), until i close these message the file wont continue loading. 3D max have a tendency to open files slowly, so i usually use this time to go and make a tea or go to wc.. It is so annoying when i come back to see, that 3D max done zero progress opening the file, and then i have a pleasure observe slow process of file opening...
