Creating a World - Fixing square projectile trails

[Gigantus]

Does this look familiar?

The fix is rather simple: the battlefield/fire/burning_smoke.tga and smoke4.tga files are not suitable for that effect. Replace their entries in the descr_arrow_trail_effects.txt file with battlefield/fire/Oil_particle_2.tga

Example:

effect fiery_boulder_smoke_flame
{
    type particle
     {
        texture            battlefield/fire/Oil_particle_2.tga

For ease of application you can download the modified vanilla file here.

Does this look better now?

If you are having the same problem with the rocket projectile then check the descr_projectile.txt file, the rocket entries. The display line should have only aimed in it, not spin.

Example:

ground_shatter
; rocket        <trail time sec> <spin prob> <spin tick> <max radius dlt> <angle min deg> <angle max deg> <erratic prob> <erratic tick> <erratic max angle>
rocket            3.5    0.6 10 0.3 120 360 0.3 12 10
; self_explode    <prob> <min sec> <max sec> [<area effect>]
self_explode    0.3 1.5 3.0
display            aimed
triangle    
texture            data/textures/arrow_test.tga
tail            0.3
