So I have a bit of a strange problem - my main camera won't render the image. In Superfly and Sketch it just renders a black square, in FireFly it'll render the lighting but nothing else. Every other camera - Aux, Face, From Left, Posing et alia - has zero problem rendering. The problem is just with Main Camera - as though it has been disabled from 'seeing' my figure. Presumably I accidentally pressed a button or tapped out a hotkey - anyone know what it was and how I can undo it?
