the #7
so yeah, i just did what he said in the post, but when i run the map, the progress just stuck in portal flow
i am not a expert on hammer, so i dont know how to fix this

[Please]

Portal Flow takes a LONG time, depending on how optimized and big your map is. If you made the map yourself, make some geomatry Func_detail.

tut if you don't know how to optimize (Moderate): https://www.youtube.com/watch?v=swBfUW-Bsxs
Basic: https://www.youtube.com/watch?v=mIy0Usc8zXU

If you got a compile log, see if anything seems out of order. If you think there is, post it here.
