stevenong Posted May 7, 2009 Share Posted May 7, 2009 Hi, It works for me and I've attached a hip file. Not sure what the second Math CHOP is doing so if you can post your hip file, we can take a look. Cheers! steven odforce_math_chop.zip Quote Link to comment Share on other sites More sharing options...

stevenong Posted May 7, 2009 Share Posted May 7, 2009 Hi, By wiring the noise2 CHOP as the first input of the math2 CHOP, the channels became chan1, chan2 & chan3 which the Channel SOP doesn't accept thus causing an error. All you have to do is to make sure the noise2 CHOP is wired as the second input to make sure the channels are named correctly. In your current file, you can select the math2 CHOP and type 'r' to reverse the inputs. To troubleshoot in the future, you can MMB (middle mouse click) on any operator to get more information so if you MMB on the math2 CHOP, you'll see the name of the channels. Cheers! steven Quote Link to comment Share on other sites More sharing options...
