A few tips:
For explosions correspond 3 effects: cannon_flare001.bmp missile_flare001.bmp and bomb_c001-c006.in general or animation directory.
If you want to disable the standard explosions just do-bmp texture 32x32 black and save as cannon_flare001.bmp missile_flare001.bmp and
bomb_c001-c006.(sample texture in Annex change jpeg to bmp)
BUT These two textures also have responsibility for other effects- cannon_flare for cannon impact explosions,missile_flare for missile fire ball.
If for a test want to disable the original cannon impact explosions just do this black texture cannon_flare.
And delete all lines except the first in the file #\animation\CANNON_FLARE.txt
bomb_c001-c006 responsible for the balls of fire after the explosion.
linked explosions cannon and missile are responsible for the effect of the explosion.
For cannon tracers are responsible CANNON_SHELL.bmp CANNON_SHELL_BLUE.bmp _green _orange _purple _red _white
as I understand do not you will need this information because you work in Lightwave, but writes:
In smokes.csv you can change all the graphics in-game effects such as flames, dust, smoke trails (such as size,
the display, speed).
In explos.csv you can change Everything that relates to the explosion - duration, delay,Initial time, final, and so on.
In metasmok.csv you have additional options regarding all smoke, smoke trails, and fires in the game.
A brief description file smokes.csv:
0;GREY_TRAIL;SMOKE_TRAIL; its missile smoke trail
2;ADDITIVE_TRAIL;ADDITIVE_SMOKE_TRAIL; its missile fire smoke trail
4;FIRE;SMOKE;its smoke plumes
8;SMALL_PARTICLE_TRAIL;SMOKE;trails before explosion
good luck
