stevenong Posted November 10, 2007 Share Posted November 10, 2007 Hi, In your hip file, there are two Copy SOPs but the switch1 SOP's stamp expression is pointing to neither of the Copy SOPs. I think the expression should be stamp("../copy2","circle",0). Perhaps that's your problem? I would also check the group1 SOP's expression since your have $CG<=9 instead of $CG<=0.9. Last but not least, welcome to the forum! Cheers! steven Quote Link to comment Share on other sites More sharing options...
