Attachment Constraint

[@petemartin5068]

That's awesome stuff! I've been trying to get a null to follow a vertex in Motionbuilder but have hit a dead end. I want to try and learn teh process behind it (scripting/constraints) I just need to get the vertex position/rotations to be the sender in a relation constraint but have no idea how to get to that :)

For extending relation constraint, you have to use c++ OpenReality SDK, in mobu there is a samples folder with "Boxes" which are relation boxes. In the openmobu repository there is, for example, a ray casting relation constraint box plugin where you can see how I get a mesh and geometry from it. Hope that helps.

@@Neill3d I see, that's why I was getting nowhere with just python alone. Thank you for the info, look forward to investigating c++ open reality 😊
