I downloaded UniHuman but my computer doesn have the required software to run the file?
UniHuman is not a program but a file for use with the program Blender 3D. Blender is an open source 3D application that runs on Windows, Mac and Linux. It is a great, fully featured software suite with multiple applications. One of which is games which is what UniHuman is targeted towards. Because I didn’t have to develop a special program to make UniHuman its development cycle was very short and it is completely integrated into blender with a familiar interface for its users. Blender can export to many popular file formats so you can still use UniHuman for whatever software you choose.
