hi guys, after adding a bunch of content to my sfm ie l4d hl2ep2 css etc, i find that the particles for the guns have turned into errors

[J3DA]

its a animation from a particle effect i found a way to remove it by not installing custom gun muzzle flashes dont install HL2 particles

[Yangzaur]

so is that only for the hl2ep2 or does it include css, l4d2,

[Yangzaur]

so delete hl2 particles?

[J3DA]

Yes
