HI Alexis, This looks like an issue with your application setting up the viewer Camera's without initializing the Camera's StateSet to global defaults. 3.0.x and 3.1.x have a bug where the internal rendering setup overrides the Camera's StateSet forcing the global defaults so would hide where

Hi Robert, Providing similar support for Camera::DrawCallbacks would be possible, there isn't the same imperative for controlling traversal, but it'd keep the public Camera API simple - it's complicated enough as it is so am reluctant to add further API to it. Sorry, I am not native English.
