difference between cave and Inspector

[Jeff]

Try the following. Does this work the way you want in Vizard?

import viz
viz.go()	

viz.clearcolor(viz.SLATE)

import vizfx
board = vizfx.addChild('chessboard.OSGB')

# Disable ambient light 
vizfx.setAmbientColor(viz.BLACK)

import vizcam
vizcam.PivotNavigate(distance=1)
