Version up sops that have a "version" parm - I use this to version up a lot of exports in tops or rops: import hou nodes = hou.selectedNodes() for x in nodes: ver = x.parm("version").eval() + 1 x.parm("version").set(ver) Send a ROP fetch to TOPs name...

Get transform and orientation from camera: string camera = "/obj/alembicarchive1/Camera2/CameraShape2"; // path to your camera @P = ptransform(camera, "space:current", {0,0,0}); @N = ntransform(camera, "space:current", {0,0,-1}); Random orient on points: ...
