You can play with next parameters:
[Library Effect]
Radius=50 -> I put 200 (The maximal size of the effect. You must give an effect a radius for it to show up as scenery. Measured in meters.)
[Particle.0]
X Scale=10.00, 10.00 -> 25.00, 25.00 (The starting size of the particle in the X, Y, and Z directions. Measured in meters.)
Y Scale=10.00, 10.00 -> 25.00, 25.00 (The starting size of the particle in the X, Y, and Z directions. Measured in meters.)
Shade=1 -> 0 (An on/off toggle that determines whether the particle is darkened at night. It is used for night shading.)
[ParticleAttributes.0]
Color Start=255, 255, 255, 200 -> 16, 16, 16, 100 (R,G,B,alpha)
Color End=255, 255, 255, 255 -> 16, 16, 16, 128 (R,G,B, alpha)
uv1=0.50, 0.00 -> 0.00, 0.00 (lower-left corner X,Y on texture)
uv2=1.00, 0.50 -> 1.00, 1.00 (upper-right corner X,Y on texture)
This is all my changes as far as I remember.
