michael Posted August 10, 2002 Share Posted August 10, 2002 <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 [0] > [76]. a second 'delete' is appended with the following options: group: n/a operation: delete selected Number is enabled Delete By Range : Start = 1, End = $N this is supposed to delete all the points except for point[0] 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 $N deletes the last point ( point[76] in this case ) Using 'Delete Non-Selected' with Start=0 and End=$N does nothing Using 'Delete Non-Selected' with Start=1 and End=$N deletes the last point ( point[76] 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?

danteA Posted August 10, 2002 Share Posted August 10, 2002 I think they forgot to mention that you also have to change the "Select _ of _" parameter to 1 of 1. They show that in their screen shot but forgot to mention it in the text. For some reason, the default for this is 1 of 2. Go figure.
