Invisible fire?

[Boler]

I was playing TTT for the first time yesterday, and while I was pissing off some people for being new (xenophobic bastards), out of the blue I heard the "I'm on fire" sound effects and died. After asking around a bit, I was finally told that someone shot me with a flare gun. The only problem with this is that I never saw any fire, or any 'flare' for that matter.

I kept playing for about an hour and started noticing that I can't see fire in this gamemode. I don't think it's a problem with Gmod specifically, because I've caught things on fire plenty of times while goofing off in single player. Has anyone else experienced this, or am I just shit out of luck here?

Its some directX related problem. What I've found has fixed it is unmounting portal, assuming you have it mounted. I heard its something about the portal fire messing with the gmod fire that makes it invisible.
This worked for me back on my old pc and for a few others. I think there's another way to fix it though.

You can enable a placeholder for fire by setting "ttt_fire_fallback 1" in the console. The convar is clientside and will be saved. This is obviously not a fix, but a workaround that will at least let you see molotov flames and such, if nothing else works.

Both posts noted, thanks.

Ah, good memories. I've also found Day of Defeat interferes, although the fix seems to be the necessity of unmounting Portal alone for most people with the fire issue.
