And just like everywhere else in sops, if you do this, its totally freeform it won't care about the lines between the points, or the connectivity, do what you want, use an edit sop, soft transforms, fine. If joints are just points like everything else in sops, you could use a transform sop to move them around. Self evident, sure, but spend some time thinking about this. This is the core of how kinefx rigs work.Ī rig is way to move joints around. If you move a 'parent' point with a kinefx node (eg rig wrangle, rig vop, rig pose) its children will inherit the motion. TLDR: Kinefx treats points connected with lines as a hierarchy.
#Houdini fx click ik solver export skin#
Given a skin with weights, and a bind pose (called a rest pose in Houdini) and a moving set of joints, move the skin. This is all assumed to be done on a static skin mesh and a static skeleton, and note that it doesn't actually move the skin, it just sets up weighting attributes. They're represented as points and lines in sops (unlike Houdini's old bone system which was up at the /obj level), so that allows for some interesting joints vs sops vs geometry interplay. More explainations below, but at a high level:Īs you think they are, joints or bones like in other packages. It also makes a point to seperate a few rigging and animation concepts which other packages tend to merge together. Kinefx covers a lot of ground, but there's a pleasing DNA share with a lot of established houdini workflows. 1.21 Export mesh with blendshapes to fbx.1.20 Change lots of blendshape detail attributes at once.
