roughly,each module (like 802DRO) is made up of pieces,normaly named 802droa,802drob and such. what the .vis file does,so as not to overload the graphics engine,it makes it so only the pieces of the module that you can see (depending on where your at) are visible at that time. Basically if your standing in 802droa you can only see b,c and d the rest won't show up. I imagine it can effect the camera also,it seemed to in the HK factory modules without a .vis file the "red" effect wouldn't work. One issue that is still not fixed and that enemies can still "see" you and shoot through wall at you in some areas. that's a walkmesh issue that currently can't be fixed.
