I 3D tracked my footage and wanted to put the plexus cube/instances in the air. But the only thing I can do is place 3D Nulls and connect them with Plexus, the cube doesn't show up. Does anyone know how to do that? Thanks
It's not clear what you are actually saying. By its nature Plexus is full 3D. The rest merely depends on your settings, but since you haven't provided any screenshots or other useful pertaining the issue I'm afraid nobody can help you much. Start by checking your camera data. Often the 3D tracker will create crazy values that require to use insanely large or small scaling of other items. Everything else realyl requires much better info.
Thanks, I will get as much information as possible asap.
