GMSC Tornado Map Series
Tornado Textures Missing
I have HL2:EP2, CSS, and the main "content pack" for these maps. However, the lightning and tornado remain invisible. The console says can't find particle f1, and same for the lightning. I have tried manually placing the particle files, but that did not work. I feel like the addon is broken. Please help!
