I’ve been hard at work the past few hours to get a neat looking day/night animation with cycles. i have used a sun, another sun(moon), and AO + Env. Lighting using the excellent cycles sky world texture. here is a test render of apart of the day cycle, 2:00 I think, took about 10 min. on CPU at 8 bounces with 750 passes. check out the high res: ![](https://blenderartists.org/uploads/default/original/4X/6/5/b/65bea90b96a78a31154d657461cf056fac965f7c.jpeg "House Day/Night Cycle") night cycle image will be coming soon. any suggestions? ### Attachments ![](https://blenderartists.org/uploads/default/original/3X/c/7/c72f96058d6c7aa216fe16ce012edd4235f13c35.jpg) ---

Here is the night test! ### Attachments ![](https://blenderartists.org/uploads/default/original/3X/9/0/90c4574c62c76854f430814ced8bd574dc986bbf.jpg) ---

And finally the finished animation! I love it! ---

That looks pretty good, Caleb! I have never tried simulating the day/night cycle in Blender before. How did you choose to animate the sun (s)? I like the various color casts that the different colored rooms generate. Very interesting. I also liked the flicker of the artificial light sources in the animation, as well as the sound effect used. If I had any critique, it would be that the bump intensity looks a little high in the animation, but maybe that’s how you like it. In any case, great work! ---

That looks really cool! The colors on the day/night cycle look believable and the color bleeding on the walls looks awesome. Nice job ---

Thanks, well the animation setup: 1. I used the cycles sky texture for the world and animated it by hand just moving it to get the correct lighting 2. I set up a Bézier circle and attached 2 suns to it that cast slightly different colors at slightly different intensities ( sun and moon) 3. I animated the sun and moon to circle around the circle and I made it so that you can infinitely loop the animation if I so needed, to save render time if I ever choose to expand it 4. I also actually animated it to be slow but the rendered out only every 5th frame so that the motion apperes a bit jumpy and also took way less time to render! thanks so much, looking back on it it probably was a little too extreme on the bump maps but your right I do like it like that haha.
