Hi All, I''ve have a base clase named CObject, for where i can derive each object Classes like (Camera, Mesh, Light, ...) I wonder what is the best way to store them in my Engine3D class. Did i''m better storing all my objects, in a LikedList for CObject type. Or do a LikedList for each derived type of object, and simply store them an Array of each Type. Did someone have an Idea... Thanks all, LowRad
