Add plugin particleprecacher.smx to your server if you care about custom particle effects in the map. The plugin is required to precache custom particle systems which doesn't work on CS:GO by default.

The plugin uses command 'sm_precache_particles <file>'. You'll have to whitelist the command so the map can execute it.

The map will work without the plugin fine, but some effects will be invisible. Just upload the .bsp and .jpg if you don't care.
