yes I found out about that after, is that really a problem? wtf...

It was never answered to, so I thought it would be good like this.

ok... so fuh said it's easy to edit particles... I don't feel the same after looking into it.

Anyways this is the rockettrail code from the Q2 engine:
Code:
/*
 =================
 CL_RocketTrail
 =================
*/
void CL_RocketTrail (vec3_t start, vec3_t end){

   particle_t   *p;
   int         flags = 0;
   vec3_t      move, vec;
   float      len, dist;

   if (!cl_particles->integer)
      return;

   if (CL_PointContents(end) & MASK_WATER){
      if (CL_PointContents(start) & MASK_WATER)
         CL_BubbleTrail(start, end, 16);

      return;
   }

   // Flames
   VectorCopy(start, move);
   VectorSubtract(end, start, vec);
   len = VectorNormalize(vec);

   dist = 1;
   VectorScale(vec, dist, vec);

   while (len > 0){
      len -= dist;

      p = CL_AllocParticle();
      if (!p)
         return;

      p->shader = cl.media.flameParticleShader;
      p->time = cl.time;
      p->flags = PARTICLE_ROTATE;

      p->org[0] = move[0] + crand();
      p->org[1] = move[1] + crand();
      p->org[2] = move[2] + crand();
      p->vel[0] = crand() * 5;
      p->vel[1] = crand() * 5;
      p->vel[2] = crand() * 5 + (25 + crand() * 5);
      p->accel[0] = 0;
      p->accel[1] = 0;
      p->accel[2] = 0;
      p->color[0] = 1.0;
      p->color[1] = 1.0;
      p->color[2] = 1.0;
      p->colorVel[0] = 0;
      p->colorVel[1] = 0;
      p->colorVel[2] = 0;
      p->alpha = 1.0;
      p->alphaVel = -1.0 / (0.2 + frand() * 0.1);
      p->radius = 3 + (1.5 * crand());
      p->radiusVel = 0;
      p->length = 1;
      p->lengthVel = 0;
      p->rotation = rand() % 360;

      VectorAdd(move, vec, move);
   }
   
   // Smoke
   flags = PARTICLE_ROTATE;

   if (cl_particleVertexLight->integer)
      flags |= PARTICLE_VERTEXLIGHT;

   VectorCopy(start, move);
   VectorSubtract(end, start, vec);
   len = VectorNormalize(vec);

   dist = 10;
   VectorScale(vec, dist, vec);

   while (len > 0){
      len -= dist;

      p = CL_AllocParticle();
      if (!p)
         return;

      p->shader = cl.media.smokeParticleShader;
      p->time = cl.time;
      p->flags = flags;

      p->org[0] = move[0] + crand();
      p->org[1] = move[1] + crand();
      p->org[2] = move[2] + crand();
      p->vel[0] = crand() * 5;
      p->vel[1] = crand() * 5;
      p->vel[2] = crand() * 5 + (25 + crand() * 5);
      p->accel[0] = 0;
      p->accel[1] = 0;
      p->accel[2] = 0;
      p->color[0] = 0;
      p->color[1] = 0;
      p->color[2] = 0;
      p->colorVel[0] = 0.75;
      p->colorVel[1] = 0.75;
      p->colorVel[2] = 0.75;
      p->alpha = 0.5;
      p->alphaVel = -(0.2 + frand() * 0.1);
      p->radius = 3 + (1.5 * crand());
      p->radiusVel = 15 + (7.5 * crand());
      p->length = 1;
      p->lengthVel = 0;
      p->rotation = rand() % 360;

      VectorAdd(move, vec, move);
   }
}


Now this is the code for fuhquake rocket trail (I believe this is all of it???)
Code:
case ROCKET_TRAIL:
   default:      
      p->ramp = (rand() & 3);
      p->color = ramp3[(int) p->ramp];
      p->type = pt_fire;
      for (j = 0; j < 3; j++)
         p->org[j] = point[j] + ((rand() % 6) - 3);
      break;
      }


and
Code:
void R_ParticleTrail (vec3_t start, vec3_t end, vec3_t *trail_origin, trail_type_t type) {
#ifdef GLQUAKE
   if (qmb_initialized && gl_part_trails.value)
      QMB_ParticleTrail(start, end, trail_origin, type);
   else
#endif
      Classic_ParticleTrail(start, end, trail_origin, type);
}


and
Code:
void QMB_ParticleTrail (vec3_t start, vec3_t end, vec3_t *trail_origin, trail_type_t type) {
   col_t color;

   switch (type) {
      case GRENADE_TRAIL:
         AddParticleTrail(p_smoke, start, end, 1.45, 0.825, NULL);
         break;
      case BLOOD_TRAIL:
      case BIG_BLOOD_TRAIL:
         AddParticleTrail(p_blood3, start, end, type == BLOOD_TRAIL ? 1.35 : 2.4, 2, NULL);
         break;
      case TRACER1_TRAIL:
         color[0] = 0; color[1] = 124; color[2] = 0;
         AddParticleTrail (p_trailpart, start, end, 3.75, 0.5, color);
         break;
      case TRACER2_TRAIL:
         color[0] = 255; color[1] = 77; color[2] = 0;
         AddParticleTrail (p_trailpart, start, end, 3.75, 0.5, color);
         break;
      case VOOR_TRAIL:
         color[0] = 77; color[1] = 0; color[2] = 255;
         AddParticleTrail (p_trailpart, start, end, 3.75, 0.5, color);
         break;
      case ALT_ROCKET_TRAIL:
         AddParticleTrail(p_dpfire, start, end, 3, 0.26, NULL);
         AddParticleTrail(p_dpsmoke, start, end, 3, 0.825, NULL);
         break;
      case ROCKET_TRAIL:
      default:
         color[0] = 255; color[1] = 56; color[2] = 9;
         AddParticleTrail(p_trailpart, start, end, 6.2, 0.31, color);
         AddParticleTrail(p_smoke, start, end, 1.8, 0.825, NULL);
         break;
   }

   VectorCopy(trail_stop, *trail_origin);
}


and lastly??
Code:
__inline static void AddParticleTrail(part_type_t type, vec3_t start, vec3_t end, float size, float time, col_t col) {
   byte *color;
   int i, j,  num_particles;
   float count, length, theta = 0;
   vec3_t point, delta;
   particle_t *p;
   particle_type_t *pt;

   if (!qmb_initialized)
      Sys_Error("QMB particle added without initialization");

   assert(size > 0 && time > 0);

   if (type < 0 || type >= num_particletypes)
      Sys_Error("AddParticle: Invalid type (%d)", type);

   pt = &particle_types[particle_type_index[type]];

   VectorCopy(start, point);
   VectorSubtract(end, start, delta);
   if (!(length = VectorLength(delta)))
      goto done;

   switch(type) {
   case p_trailpart:
      count = length / 1.1;
      break;
   case p_blood3:
      count = length / 8;
      break;
   case p_smoke:
      count = length / 3.8;
      break;
   case p_dpsmoke:
      count = length / 2.5;
      break;
   case p_dpfire:
      count = length / 2.8;
      break;
   default:
      assert(!"AddParticleTrail: unexpected type");
      break;
   }

   if (!(num_particles = (int) count))
      goto done;

   VectorScale(delta, 1.0 / num_particles, delta);

   for (i = 0; i < num_particles && free_particles; i++) {
      color = col ? col : ColorForParticle(type);
      INIT_NEW_PARTICLE(pt, p, color, size, time);

      switch (type) {
      case p_trailpart:
         VectorCopy (point, p->org);
         VectorClear(p->vel);
         p->growth = -size / time;
         break;
      case p_blood3:
         VectorCopy (point, p->org);
         for (j = 0; j < 3; j++)
            p->org[j] += ((rand() & 15) - 8) / 8.0;
         for (j = 0; j < 3; j++)
            p->vel[j] = ((rand() & 15) - 8) / 2.0;
         p->size = size * (rand() % 20) / 10.0;
         p->growth = 6;
         break;
      case p_smoke:
         VectorCopy (point, p->org);
         for (j = 0; j < 3; j++)
            p->org[j] += ((rand() & 7) - 4) / 8.0;
         p->vel[0] = p->vel[1] = 0;
         p->vel[2] = rand() & 3;
         p->growth = 4.5;
         p->rotspeed = (rand() & 63) + 96;
         break;
      case p_dpsmoke:
         VectorCopy (point, p->org);
         for (j = 0; j < 3; j++)
            p->vel[j] = (rand() % 10) - 5;
         p->growth = 3;
         p->rotspeed = (rand() & 63) + 96;
         break;
      case p_dpfire:
         VectorCopy (point, p->org);
         for (j = 0; j < 3; j++)
            p->vel[j] = (rand() % 40) - 20;
         break;
      default:
         assert(!"AddParticleTrail: unexpected type");
         break;
      }

      VectorAdd(point, delta, point);
   }
done:
   VectorCopy (point, trail_stop);
}


I honestly tried to do it, and make it myself, since fuh said it was easy. But I sadly am not able to do it Sad. If someone could PLEASE help me here, it would be greatly appreciated, thanks!

I tried q2 evolved...its great, but the trails look sorta lame ingame compared to the screens...I like the Fuh's qmb modified trails better.



1024 image scaled to 512

To me ingame the trails look nothing like the pics...I was thinking I had to get the newer version, untill I looked at the screens I took.

It would be cool if you could control the transparency of explosions and trails!
