It may be one from many, you should search the plugin if you want that exact effect... but from that I see, the following messages *could* be used, from messages_const.inc:
Code:
#define TE_SPRITE_SPRAY 110 // Spray of alpha sprites
// write_byte(TE_SPRITE_SPRAY)
// write_coord(position.x)
// write_coord(position.y)
// write_coord(position.z)
// write_coord(velocity.x)
// write_coord(velocity.y)
// write_coord(velocity.z)
// write_short(sprite index)
// write_byte(count)
// write_byte(speed)
// write_byte(noise)
#define TE_SPRAY 120 // Throws a shower of sprites or models
// write_byte(TE_SPRAY)
// write_coord(position.x)
// write_coord(position.y)
// write_coord(position.z)
// write_coord(direction.x)
// write_coord(direction.y)
// write_coord(direction.z)
// write_short(modelindex)
// write_byte(count)
// write_byte(speed)
// write_byte(noise)
// write_byte(rendermode)
#define TE_PLAYERSPRITES 121 // Sprites emit from a player's bounding box (ONLY use for players!)
// write_byte(TE_PLAYERSPRITES)
// write_short(playernum)
// write_short(sprite modelindex)
// write_byte(count)
// write_byte(variance) (0 = no variance in size) (10 = 10% variance in size)
And there could be more that can do the same effect or the exact effect by default.
These values are used in messages with SVC_TEMPENTITY, the contents of the message is described in the comments.
