We all remember the 'Eerie Orbiting Fire' halloween unusual effect, and it was very popular, eerily popular I could say. Well here is my rendition of it, similar to 'Scorching Flames' or 'Burning Flames', but eerier.
NOTE:

Ok, so 100+ ratings later on my old post and being on the second page of most popular for the week, it says its incompatible. Just because it's not a .obj or .tga, doesn't mean it's incompatible! Of course it won't be those file types, it's a PARTICLE effect, not a MATERIAL, so it's a .pcf file! Ughhhh ;_;
So this is the .pcf file, once again, but I have included a .obj stock head so it still passes as an item, the workshop probably doesn't get many .pcf files and scans only for materials, and essentially .obj files.
