I have a model of an airplane done in another program where the model is broken down into multiple mesh layers. I exported it as an alembic and imported to houdini. When I did, parts of the mesh were at different Y positions. I couldn't figure out what was going on and by accident clicked on the “Toggle local view context” menu item when I right clicked in the viewport. That caused everything to move into the correct position. I've tried looking up that command to see what it does but can't find it. I thought if I fired it again, that the mesh items would move back to their original position, but they don't. So I'm a little confused on what that's about.
Secondly, I've seen some videos where people are in houdini and in the viewport there's a window that shows the heirarchy of a mesh like what I have. I can't figure out what that window is called or how to open it. Does anyone know what I mean?
