kni8_2k Posted June 1, 2017 Share Posted June 1, 2017 (edited) Hi, I wanted to know if anyone has encountered this problem. I'm exporting rigid bodies from Houdini as Alembic to Maya, and noticed that when I convert that to Join animation in Maya there is a two frame shift at the beginning which puts all the pieces out of alignment I then thought this was from the script, but looking at maya I saw that the pivot was moving on frame 1-3 then staying somewhat stable. after blaming this on Alembic(lol) I went back to houdini and found that if you switch the dop import node to create points to represent objects. you can see the shift happen with the picture using a trail sop. This does not effect the actual sim geo, but is something that is happening on the underlying data. Which messes with conversion to bones. Does anyone know how to prevent this ? I've included a hip file. Thank you. pivot_shift_example.hip Edited June 1, 2017 by kni8_2k Quote Link to comment Share on other sites More sharing options...
kni8_2k Posted June 1, 2017 Author Share Posted June 1, 2017 Looks like on the RBD Packed Object node i need to click on Solve on Creation Frame in order to keep this shift from Happening. This seems to have fixed it. Cheers Ali Quote Link to comment Share on other sites More sharing options...
