stageview is blank/not rendering #13

Closed uncojohnco closed 5 years ago

When using usdview for the first time the stageView is black i.e not rendering(?)

might be because I'm using a VM...

usdview extras/usd/tutorials/convertingLayerFormats/Sphere.usda

This is resolved, had to enable the nvidia video card on my laptop. I had it disabled to use the intel video card to save battery power :upside_down_face:
