<Win2K, Houdini 5.5.52>
I'm doing the Contrail Tutoril from Techimage and I'm running into a problem:
in part 1 (pg13) points are selected and grouped to act as emission points, then a facet is applied to make sure there are no shared points
the network branches here:
a ) a circle is copied to the points to give a larger surface to emit smoke from
b ) points are deleted, leaving only one, to be brought into CHOPs
but this is where things don't work as in the tutorial...
in the 'b' branch of the network a 'delete' is appended to the 'facet' with the emission_group in 'Group' and Delete Non-Selected for 'Operation' > this works fine, leaving 77 points  > .
a second 'delete' is appended with the following options:
operation: delete selected
Number is enabled
Delete By Range : Start = 1, End = $N
this is supposed to delete all the points except for point
but it doesn't, it does nothing.
I've tried to play around with some of the options but it hasn't done any good...
Setting Start to 0 and End to $N deletes the last point ( point in this case )
Using 'Delete Non-Selected' with Start=0 and End=$N does nothing
Using 'Delete Non-Selected' with Start=1 and End=$N deletes the last point ( point in this case )
using emission_group in 'Group' deletes all the points
so is it me?, Houdini 5.5.52? the weather?
has anyone else tried this tutorial?
