well i figured it out lol i changed every fxt_"____".iwi related to smoke and explosion's to narrow it down, looks pretty funky.
now just need to figure out how to assign it to specific weapons. im assuming id have to create a .ff file and code something but i have no idea where to start.
the specific files for muzzle flash seem to be "fxt_fire_flash.dds" and "fxt_fire_gas_flash.dds"
anyway here's some screenshots
