i've been in the steam chat getting some help on this problem but I still can't seem to fix it. My bvis is not responding and sometimes just crashes. I've tried to compile my map on vbct and still gets stuck. I figured there was a leak so I just made a huge box for the skybox that contains everything and I'm still getting stuck. This all started happening when I started adding a shit ton of displacements and some props. here is the link to the ginormous sky box. https://drive.google.com/file/d/0B8Fdv9mIgcM5V01YUk5zSTQ1WEk/view?usp=sharing Thanks for helping I really appreciate it guys it has been really frustrating. edit: vbsp is getting stuck. i don't know what vbis is.
