[BUG-228587] [EEP] The glowing effect is too strong with particles #6635

What just happened?

The glowing effect is too strong with particles.

Seen from far away it looks different than in the previous versions. You can't see the particles anymore and it looks like a big glowing ball.

What were you doing when it happened?

Using the following particle script:


default
{
    state_entry()
    {
        llParticleSystem(
        [
            PSYS_SRC_PATTERN, PSYS_SRC_PATTERN_ANGLE_CONE,
            PSYS_SRC_BURST_RADIUS, 0.0, //(float) Flame offset from source in meters
            PSYS_SRC_ANGLE_BEGIN, 0.0,
            PSYS_SRC_ANGLE_END, 0.0,
            PSYS_SRC_TARGET_KEY, llGetKey(),
            PSYS_PART_START_COLOR, <1.0, 0.5, 0.0>, //(vector) RGB value that controls edge color of the flame
            PSYS_PART_END_COLOR, <1.0 , 1.0, 1.0>, //(vector) RGB value that controls core color of flame
            PSYS_PART_START_ALPHA, 1.0,
            PSYS_PART_END_ALPHA, 1.0,
            PSYS_PART_START_GLOW, 0.6, //(float) Adds volume to fire, at 0.0 the fire looks flat
            PSYS_PART_END_GLOW, 0.0,
            PSYS_PART_BLEND_FUNC_SOURCE, PSYS_PART_BF_SOURCE_ALPHA,
            PSYS_PART_BLEND_FUNC_DEST, PSYS_PART_BF_ONE,
            PSYS_PART_START_SCALE, <1.2, 1.2, 0.2>, //Controls start-dimensions of the flame (important to adjust to engine size)
            PSYS_PART_END_SCALE, <0.5, 0.5, 0.0>, // Controls end-dimensions
            PSYS_SRC_TEXTURE, "", //Place your texture UUID here
            PSYS_SRC_MAX_AGE, 0.0,
            PSYS_PART_MAX_AGE, 1.3, //(float) Factor that controls length of afterburner (higher value is longer flame)
            PSYS_SRC_BURST_RATE, 0.0, //(float) Factor that controls density (shorter interval is denser flame)
            PSYS_SRC_BURST_PART_COUNT, 1, //(integer) Number of particles emitted per interval
            PSYS_SRC_ACCEL, <0.0, 0.0, 0.0>, 
            PSYS_SRC_OMEGA, <0.0, 1.0, 45.0>,
            PSYS_SRC_BURST_SPEED_MIN, 1, //(float) specifies minimum random speed in m/s per particle (Controls behavior & length of flame)
            PSYS_SRC_BURST_SPEED_MAX, 2, //(float) specifies maximum random speed in m/s per particle (Controls behavior & length of flame)
            PSYS_PART_FLAGS, PSYS_PART_INTERP_SCALE_MASK //PSYS_PART_FOLLOW_SRC_MASK makes flame follow moving vehicle and PSYS_PART_INTERP_SCALE_MASK makes textures scaleable as they emit
        ]);
    }
}

What were you expecting to happen instead?

Glowing particles should look like in the previous versions.

I can reproduce this on EEP but for me it's quite a subtle effect. On the EEP viewer the glow effect looks stronger, which means that you don't see the details of the particles as clearly. I'm not sure if this is a bug or whether it's just a case of "things look a little different on EEP".

I've attached "particle glow at distance.png" which is using the particle script in the Description.
