Hi andreas, hi dirk, thanks for the quick answers. I have another little question for you always regarding the camera management for the antialias. Since i am working to an application that uses multiple viewports depending on the same camera and that the application already uses a stereocameradecorator, i'd like to know if i can achieve the same results as the tiledcameradecorator just altering the original camera projection matrix.
