Ben sana bunu çevireyim... F9 bas orda VIS 'e " -full " ekle sorunun çözülecek.. Haritandaki bir üçgen yüzeyde fazla parlaklık var...Leaf portal saw into leaf
This occurs when you have a leaf which isn't entirely convex, so that at one position within the leaf you can look out of the leaf and see back into it.This is often a difficult error to track down as changes in the brushes in your map may cause an increase in leafportal errors. Brushes with many faces sharing the same vertex, such as spikes, are particularly common causes of this error. Doing a -full VIS often fixes this problem. If all else fails, changing the brush to a func_wall may solve the problem.
