watchman Posted January 29, 2009 Share Posted January 29, 2009 hi, this is my first post here, although I'm sneaking around for a while. Usually, I'm able to find all the answers to difficult questions just by using the forum search, but this time no luck. Simple question: Similarly to DOP Object activation expression: $F<5 && $F>15 how can I translate this expression to a CHOP channel? I tried to type this expression in ExpressionCHOP - not working, syntax must be different. I'm aware that I could keyframe a spare channel and fetch its value to CHOP, but I'm wondering if there's an easier solution. I got loads of RBD Objects in multiple DOP networks and I want the ability to control their activation from a single place, and also the ability to use DelayCHOP on some of them. Is using CHOPs a good way to do that at all? thanks, nem Quote Link to comment Share on other sites More sharing options...
edward Posted January 29, 2009 Share Posted January 29, 2009 If you look in the helpcard for the Expression CHOP, you'll note that there's the local variable $I which gives you the current index being evaluated for the CHOP. For default channel ranges, this is roughly the same as $F +/- 1. Quote Link to comment Share on other sites More sharing options...
watchman Posted January 29, 2009 Author Share Posted January 29, 2009 great, thank you very much, the expression is working since I've changed $F to $I. Quote Link to comment Share on other sites More sharing options...
