Bug with a flashlight Half-Life 2 (build 2187)

Could please someone help me I have a weird flashlight bug where flashlight doesn’t light some areas like walls. In the vents flashlight doesn’t light surfaces at all it’s all pitch black inside is this a thing now with the Old 2004 version of Half-Life 2 is there any fix for that?
It only happens on DirectX 9.0 but everything works fine on Directx 8.1

Why do you use 2187? :thinking:

Well for many stuff like old school speedrunning and just for nostalgia i also have collectors edition but it has the same problem with a flashlight

It’s probably a map bug. I’m not a mapper, but you shouldn’t worry too much about it.
