Depending of your scene sometimes require just of billboards or shapes without geometries known as Sprite3D in away3D <what it could be a transparency material in C4D>, do not have mouse event enabled they are considerer as low pol meshes and their use is just limitated as flat image, hence they do not create shadows by the reflection of light( e.g. directionalLight ) but the can be affected by light themselves, the other option is to add a plane geometry and dress it with the material wished, it has mouse event enable and can be handle as a 3D mesh, (see
how to add 3d model with away3D), also can create shadow by the reflection of light. Otherwise just adding a bitmap to a movieclip it could be an option its use is known as a flash display object and of course have to be treated as 2D. The idea is to know to deal with these to set up the best your scene that include a beautiful and fast render of course.
