I'm trying to make a loop of a camera tracking forward in z-space over a plane with some noise shaders in the bump channel. I'm going for a texture that looks like gently rippling water. I have my noise shaders set to loop at five second intervals. The problem is that I can't figure out how to match the first frame to the last frame because the noise patterns don't match in z-space. The bump texture on the first and last frames appears to match perfectly when I look at it in the viewport, but when I render, the noise patterns are completely different.
