I’m modeling an address book and have a mesh with tabs (UV mapped). I’ve created one .png with a paper surface image and the letters of the alphabet in black. Animated a slow camera pan. After rendering a targa sequence the texture appears in place but there seems to be another texture or layer or grain that doesn't move. Its mostly noticeable around the black fonts but once you see whats going on its everywhere. Almost as if there is a slight transparency.
