Quote from Vayadid you use another map's lighting or did you make your own from scratch? I would check out this - https://developer.valvesoftware.com/wiki/Sky_List - and take the settings that match your skybox
Layout wise a playtest is the best way to get a lot of feedback. not sure of alaska>EU time difference?
Sorry for the crazy late reply!
All I did was grab the global lighting entities from Office as that was the starting idea I was building from. My color and lighting scheme has really been the biggest sore area of my mapping. Been playing Black Mesa and the lighting in the maps have been showing me that I've got some work to do.
The skybox is also pulled from office with a weak attempt to move the buildings around into the gaps between buildings.
As for the layout I haven't had a chance to touch the map for about a month now and today I was able to sit down and just sketch what my current layout looks like and came to the conclusion that the parking lot is just an old bomb site from a WAY early iteration from when the B site was directly under the A site and going to be replacing the parking lot so the layout will be going under another massive change and wouldn't want to waste peoples time with a layout I know is going to be changed.
Will be pretty much remaking the map from scratch at this point, along with the new name.
