From how you all blew something so small up, I can tell that you all are libtards. Just worthless fucking libtards.
I did everything but the Hollow Caulk Box and Hollow Sky Texture thing. How do I do it?
Mine never worked without doing this.. go to textures, usage, all, select the checkered default texture and draw a brush around your map (preferably larger than the map) and on the top tools bar youll see a red box, you might have to look for it but it will say hollow. Select the brush and press that button. Go to textures, usage, sky and select a sky similar to yours. If your map is dark, select a darker texture, if its light select one that's about as light as your skyboxmodel. Or if its available use your skyboxmodel texture.
Aye mate you don't know me so y don't you shut tf up ok buddy
Thank you, it finally worked!
