Should be fixed now, thanks

Doesn't seem to appear in episode 1

@ctwoafiveb
You're doin god's work, thanks

nice, finally underwater effects in water hazard, game is finally playable.thx

Now updated with fixed overlays for most maps that were missing them! Turns out it was a very simple material issue and the fixes already existed, I somehow just forgot they were a thing lol

Is it possible to add underwater shader in part where it missing?

why isnt there a fix for that :(

oh yeah i hate valve didnt fixed the water effect missing in most of the hl2 maps, specially in route canals and water hazard where u NEED to go underwater. is crazy to think.
