j00ey Posted March 20, 2021 Share Posted March 20, 2021 I'm following this great youTube from Christopher Rutledge and having a problem with the skeleton mirror SOP. If I leave the group field set to * it mirrors the whole skeleton, which gives me duplicated joints - but if I group some points and use that group name it errors out. In fact as soon as the input has a point group at all it throws an error - even if I leave the group field set to *. The node interface appears to be different in my build [18.5.499] so I wonder if it's currently broken... I tried the same thing with a Mixamo skeleton in case there's something wrong with my skeleton, and I've tried group joints SOP, group SOP etc etc input but the behaviour is the same..

j00ey Posted March 21, 2021 Author Share Posted March 21, 2021 Ah ok, interesting, it doesn't work in 18.5.499. It's doing the same thing as in my scene, I guess it must be a bug in that case. Thanks very much in any case! Quote Link to comment Share on other sites More sharing options...
mr.prudov Posted March 21, 2021 Share Posted March 21, 2021 Ok, well. Please try to report a bug to sidefx. Later I’ll try to implement this in vex if this can help, or you can just download the previous Houdini build Quote Link to comment Share on other sites More sharing options...
j00ey Posted March 21, 2021 Author Share Posted March 21, 2021 Yes I've submitted a bug report. If you do do a vex version I'd be very interested to see that.. Quote Link to comment Share on other sites More sharing options...
mr.prudov Posted March 21, 2021 Share Posted March 21, 2021 (edited) huh dig some theory and here it goes. mirrors only about the origin here is the cool stuff about the mirroring matrices, if someone wants to know more the basic idea is this: i've only implemented the rotation part. mirror_rig_vex.hiplc Edited March 21, 2021 by mr.prudov Quote Link to comment Share on other sites More sharing options...
j00ey Posted March 22, 2021 Author Share Posted March 22, 2021 Thanks Nicolai - I will see if I can wrap my head around what's going on in your file. I've never been too good at matrix maths but learning gradually! The bug is fixed in 18.5.523 daily build too btw. Quote Link to comment Share on other sites More sharing options...
