j00ey Posted November 7, 2018 Share Posted November 7, 2018 Can someone tell me what I'm doing wrong in this scene? It's a dummy scene with the same problem I ran in to and can't fix. I have a load of geometries which are pretty heavy and I want to instance them onto some moving and spinning points as packed disk prims. I'm setting the rotation just by picking a random axis and an angle based on the frame number and setting orient. I'm using the same vector and floats to set 'w' in order that I can get correct motion blur but it's not correct - it seems that the geo is rotating around the wrong pivot. [In this scene it's not actually hugely obvious that it's wrong because the scale is small but my actual scene is in the thousands of units and it's very obvious]. If I copy and pack with a copy SOP it appears to be correct but not instancing. I suspect I need to edit some primintrinsics, eg pivot, but everything I've tried so far doesn't work and I can't spot any difference in the intrinsics for either method. Any ideas welcome... Thanks for reading angular_velocity.hiplc Quote Link to comment Share on other sites More sharing options...
