saca Posted November 24, 2019 Share Posted November 24, 2019 hi, I create test scene, Random timeshift on the points. I have read some tutorials, "CopyStampSOP" and timeshift. "CopyStampSOP" version is good well. similar SOP "copyToPointsSOP", it's fail. What expression should I write for timeshift? thanks Time_Shift_Random_v002.hipnc Quote Link to comment Share on other sites More sharing options...

As number of point in this case will be number of loop iteration.
