Idea for viewer is to replace textures with free one set, so no copyright infringement will take place and only map files are needed (e.g. somename.unr) without texture or other game packages. Textures are packed inside the binary so only level-file (*.unr, *.run or *.wot) is needed for viewing levels/maps.
Viewer Binary is for 386-architecture (Debian Linux 8). Video card used in development was NVIDIA GT730. Needs OpenGL 3.3. (so e.g. VirtualBox is not enough, since it provides only OpenGL 2.1). No installer is provided; just gunzip uviewer.gz and place uviewer binary in the path somewhere (e.g. /usr/bin/) with execution permissions.
I decided not to include lightmaps, since the generation of those was slowish and not eastethically very appealing. Instead I tried different light rendering schemes with GLSL. The user interface, "xmanager", is written by me and has still some issues and memory leaks to be corrected.
UViewer 64-bit version 0.928 (little less unstable)
