It is clear that I need to defining the 2D polygon of the whole. But something is just not perfect, maybe the masking or I don't know...actually I have already tried out with every variation of the fill_control and there was no effect
my 2D script:
WALLHOLE2 5, 98, fp, fbp, fx, fy, fa,
a/2,0,0,
a/2+p, t, 0,
-a/2+p, t,0,
-a/2, 0, 0,
a/2, 0, -1
where 98 is the fill_control
fp, fbp, fx, fy, fa the other parameters of the fill, ldefined in the parameters
the points of the polygon are parametrical and that would like to be a trapez. (rombusz magyarul...ha mar en is az vagyok
)....
if I am right this new definied polygon should be appeared in 2D, isn't it?
