Hello i am Customizing the track validity areas in 3DSimED3 and i come into a result that we have limited number of surfaces in surfaces.ini file and the objects in the kn5 are like zillions.
For example i want to add the grass from one place as valid track and as i make it 1 in the surfaces.ini all of the grass become valid to race on.
what i want is just to limit it into that specific grass and the other grass will be unvalid.
i tried to create more surface edits, copied the current surface of grass, pasted it and changed the surface name only and thats it.
where i'm wrong.
i have doubts on the naming as i don't know where to put that id in surfaces as i see it nowhere in surfaces.ini.
i have been trying from 3 days and now i'm pulling my hairs out. please help in this regard.

call valid grass pieces like
1GRVALID_somename1
1GRVALID_somename2

in "surfaces.ini" make a section:

[SURFACE_4]
KEY=GRVALID
FRICTION=0.93
DAMPING=0.04
WAV=gras.wav
WAV_PITCH=0
FF_EFFECT=1
DIRT_ADDITIVE=1
IS_VALID_TRACK=1
BLACK_FLAG_TIME=0
SIN_HEIGHT=0.002
SIN_LENGTH=1
IS_PITLANE=0
VIBRATION_GAIN=0.1
VIBRATION_LENGTH=1

For normal invalid grass like
1GRASS_somename1
30GRASS_somename2
you dont need anything in "surfaces.ini", because AC also has defaults in
