"Remake" was the public BETA, it has been discontinued for some time now.
ReCap is primarily about point clouds. It's not intended to work with other formats, but rather process point cloud data (including that generated from the online photo-processing tool) for consumption in other programs like 3DSMAX. The only currently supported method to view items in ReCap with point clouds is to add Navisworks files for a pseudo-augmented reality view (and it's pretty slick, too).
A better supported option would be to load the 3DSMAX model(s) and the ReCap point cloud in Navisworks Simulate or Manage.
