UE Viewer
Viewer and exporter for Unreal Engine 1-4 assets
..." (it was left from the older name "Unreal MODEL viewer"). UE Viewer is a viewer for visual resources of games made with Unreal engine. Currently, all engine versions (from 1 to 4) are supported. We are using our own build system to compile UE Viewer. You may find a Perl script in Tools/genmake. This script generates makefiles from some human-friendly project format. After that you may build generated makefile using 'nmake' for Visual Studio or 'make' for gcc.
