Hey everyone lets get a few things outta the way: I was moving a group of objects and brushes, deselected all brushes which enclose the map (the skybox) and went on about working on some other work. When I got to checking it out it is completely black minus a select few props. Now in all my years of mapping I haven't heard of this suddenly just happening. Things to note: - No leaks reported in log and no pointfile generated. (Even did an extra check by enclosing the skybox in a bigger solid enclosed box but to no avail) - Light does exist in the map in the form of a light_environment along with other smaller lights for certain areas. - Vrad used to do 18 bounces, now it goes up to 100. - Both vis and rad set to fast for development and testing reasons. - Only recent changes were: Moving solid geometry, converting some solids to func_detail and adding of prop_satics. - I do have an env_cubemap which is set to default. Any ideas or help would indeed be appreciated.
