Hi Zach, I thought about this idea but it's will be a little bit complex because I have to change a big part of the code of my program to check that every hit computing I do has a test on the HUD name. But maybe it will be the simplest way.
Thanks 2006/12/4, Zach Deedler <[EMAIL PROTECTED]>:
Benoit, You can also traverse back up the tree, and throw out intersections you don't like. If you name your HUD something, then you can throw out that intersection, by checking the name of everything the pick intersected.
