To get the other two different flocks from the link to circle above the course
put the kn5 files into the track's folder and add to the models ini file

Code:

[DYNAMIC_OBJECT_0]
PROBABILITY=100
MULT=1,1
FILE=flock_1_dyn.kn5
POS_MODE=RANDOM
RND_POS_CENTER=-500,-600,0
RND_POS_RANGE=0,0,0
VEL_MODE=RANDOM
RND_VEL_BASE=1,0,1
RND_VEL_RANGE=0.8,0,0.8

[DYNAMIC_OBJECT_1]
PROBABILITY=100
MULT=1,1
FILE=flock_2_dyn.kn5
POS_MODE=RANDOM
RND_POS_CENTER=-5000,-520,0
RND_POS_RANGE=0,0,0
VEL_MODE=RANDOM
RND_VEL_BASE=1.5,0,1.5
RND_VEL_RANGE=0.8,0,0.8

For the CSP extension

Code:

[SHADER_REPLACEMENT_...]
MATERIALS=flock_1
PROP_0 = distortion, 7
PROP_1 = frequency, 0.75

[WRAP_MESHES_...]
NAME = flock_2
MESHES = flock_2
PIVOT_POS = 461.35, -815.67, 383.63

[ANIMATED_...]
NODE = flock_2
WINDMILL_DIR = 1, 1, 1
WINDMILL_DIR_EXP = 0
WINDMILL_DIR_BOTH_SIDES = 1
SPIN_AXIS = 0.01, 1, 0.01
SPEED_MULT = 0.0012
WIND_SPEED_KMH_MIN = 0
WIND_SPEED_KMH_MAX = 120
WIND_SPEED_KMH_STOP = 140
LAG_UP = 0.0
LAG_DOWN = 0.0
LAG_BRAKING = 0.0

[WRAP_MESHES_...]
NAME = flock_1
MESHES = flock_1
PIVOT_POS = 461.35, -815.67, 383.63

[ANIMATED_...]
NODE = flock_1
WINDMILL_DIR = 1, 1, 1
WINDMILL_DIR_EXP = 0
WINDMILL_DIR_BOTH_SIDES = 1
SPIN_AXIS = 0.01, 1, 0.01
SPEED_MULT = 0.0012
WIND_SPEED_KMH_MIN = 0
WIND_SPEED_KMH_MAX = 120
WIND_SPEED_KMH_STOP = 140
LAG_UP = 0.0
LAG_DOWN = 0.0
LAG_BRAKING = 0.0

And lastly - the settings for anti-aliasing matter a lot with such tiny silhouettes. When using 4x and no FXAA the flocks look their best in 1080p. With FXAA and 0x MSAA they are ok but a bit less visible.
