how do I remove the “flying Robot”

[Jeff]

Sorry, that's a Vizard 4 command. The following should work for Vizard 3:

import viz
import vizact
import steve

viz.go()

steve = steve.Steve(pos=[0,1,7],euler=[180,0,0])
court = viz.addChild('court.ive')

subWindow = viz.addWindow()
mask = viz.addNodeMask()
steve.setMask(mask)
viz.MainWindow.setCullMask(mask)
