All of our models was made on the 3dsmax, and we are able to provide uncollapsed modifier stack only for the 3dsmax, but if you'd need the lower polygon version at other programs, please contact with the support, and we will convert the reduced mesh to requested format. For this product there's 3 different 3dsmax files included. "Set" is uncollapsed, it's a file where you can make changes at the model. "Hipoly" is collapsed to hipoly with all the modifiers history cleaned to make it trouble free while using at other programs "Studio" is the file with all rendering setups that we used to make the previews renderings.
