I'm combining the PNG sequence animation with live action footage in After Effects.  This allows me to better blance lighting, grade the background footage and matte forground objects into the scene.  This particular scene has 32 layers of elements, fire, smoke, sparks, bullet hits and many others.  The Poser animation is sandwiched somewhere in the middle of all this mayhem.  The "table" is in the footage of the scene and not a Poser prop.

Everything worked great and the reflection came out perfect, so I'm home free.
