#num particles is per second(I think it's slightly faster to for add new? Untested). So particle_system_add_new will spawn a whole bunch as you found out.

You can use particle_system_burst (particle_system_burst, "psys_", pos, 1), <- this last number is the total amount of particles to spawn. In this case 1.

Ok so now say you wanted to work out how to make an effect last 3 seconds.
If your particle system #num parrticles is 2 per second, then bursting (particle_system_burst, "psys_", pos, 6). 6 total particles will take 3 seconds to end.

Hope that makes sense

Have you tried adding backfaces in OpenBRF?
(Right click model > Backfacing faces > add)

You can add your own particles. You just have to do it using the warband system.

All a particle system does is really efficiently spawn and destroy the same mesh as many times as you tell it to. (tho its slightly more complicated than that)

The meshes usually have some form of transparency to blend well. Look up prt_mesh_fire_1 in the particles_2.brf its a really great example. Pay attention to its material and transparency settings.

Each mesh that is spawned by the particle system is then controlled by a number of variables in the particle system code, including but not limited to: color, gravity, transparency, rotation, velocity(world), time alive, emit box size, etc. When you combine all these variables and particle meshes together. You get effect that you want.

How to add them: Use module_particle_system.py-  each particle system points to a mesh to spawn, can be any shape or size, but usually its just a billboard mesh.
How to attach them to items: Use module_items.py -

Code:

["torch",         "Torch", [("club",0)], itp_type_one_handed_wpn|itp_primary, itc_scimitar, 11 , weight(2.5)|difficulty(0)|spd_rtng(95) | weapon_length(95)|swing_damage(11 , blunt) | thrust_damage(0 ,  pierce),imodbits_none,
 [(ti_on_init_item, [(set_position_delta,0,60,0),(particle_system_add_new, "psys_torch_fire"),(particle_system_add_new, "psys_torch_smoke"),(set_current_color,150, 130, 70),(add_point_light, 10, 30),
])]],

The important stuff here is (set_position_delta,0,60,0),(particle_system_add_new, "psys_torch_fire")- which will attach a particle system from  module_particle_system
You can also use (particle_system_burst, "psys_your_particle", pos2, 1), which bursts a total amount of particles and a position you have.

Limits are: normal processing limits dont spawn too many. Hard coded randomization for vector speeds and rotations. Limited Vector control (world position only).

Trails- there are no trail renderers. If you attach a particle system to an object and the object is moving tho, a particle trail will be created if that's what you mean.

You cant use any system external to mount and blade to create particles. Although if you know what you're doing I guess you could bake particles to textures.

For advice on starting out- I suggest start by modifying the torch item slightly and see what happens. Then try modifying the torch_fire particle system and see what happens. Then try creating your own particle system. Then try creating your own mesh. Then try attaching your particle system to items and scene props.

Yeah you can do some pretty great custom particles using the system.
Kind of a wide topic tho. What exactly do ya want to do and I'll point ya in the right direction?
