"I think you need at least P5 to be able to animate textures."

Well the way I've been doing it is just simply applying textures to different squares, then moving them in the 3D space in such a way that it appears to animate. Each square must be identical in size, and be place in the exact same spot when in frame (though it doesn't matter where they are out of frame), then just replace them one frame at a time to create an animation.

So I guess if I had multiple frames of that flame flickering, I could do that, but the package only comes with one texture for the flame.
