Thanks Utkarsh!

This change would take a build right? Can't do it right now =/

My goal is to know what should I do after a

cameraInstance.Pitch(90)

and before a

Render()

In order not to get the warning

Resetting view-up since view plane normal is parallel

I've tried

cameraInstance.ComputeViewPlaneNormal()

but with no sucess...

Do you know why and can explain me the reason of this warning ?
More important, how to get rid of it? hahaha
My goal trying to print the camera attributes was to debug this info!

Thanks in advance!
