I have always wondered why RPC trees seem to do a pirouette when your camera moves by them in an animation. Does anyone know why this happens and how to stop it? I used to have alibrary of trees that I made by rendering each RPC and them mapping the image on to two 2D planes that I put together in a cross shape. This helped the "moving tree" problem, but I have since lost that library.
I would like to use the RPC trees, but don't want them (or their shadows) to look like they are moving in an animation.
