Hi, I'm having a look at the excellent bGUI extension code. I'm wondering how Temechon did to display a vertical orthographic panel in front of the main scene. I'm just discoverying that a BJS scene has an array of active cameras : https://github.com/Temechon/bGUI/blob/master/src/GUISystem.js#L70 and meanwhile a single active camera. So I don't really get how two different cameras can be used in the same time ... I just don't get the global mechanism to tell the engine to render this, this and this with a camera and that, that and that with another one in the same scene, as I can't find in the bGUI code that there would different scenes to be rendered. Seems mysterious to me ...
