Multilight dawn to dusk animation It works!

I had mentioned earlier on the forum a theory on how to do this. I suggested creating an emitter for each hour of the day and then fading between them.
I managed to get it to work and it is very cool. but I don't know the colours and intensity for each of the emitters. Can anyone help with this?

Huh?
We're talking about a multilight animation here.

I would think you need an emitter for every 10 minutes or so to have a smooth movement of the shadows...?

You're right it is a problem. It turns out to be a lot of sliders too.

You would probably need a massive amount of RAM to do this.

I've done it with the sketchup exporter, but what do you know... It is at work, and they don't have a frame to animation exporter.

Good on you mate for testing that
I'd love to see the results too!
I thought about the same too some time ago but never got around to testing. I also figured it would need quite a lot of panles to get it smooth. Though I also thought that if the panels were divided up to have triangular overlaps so that as panel one starts to go off triangle two is starting. I know this may also require a graduated MXI emitter to these panels though that could be fairly easy too!
so show us your results mate please!

Here is the sample id did up in about 20 minutes.
It is super easy to do, I imagine that the process could be automated somehow with a plugin, and with the proper lighting levels. I based the color of the lighting on a kelvin chart that I found.

great, but how about a more
smooth movement?

That's a pretty cool effect. I like how the transition is not so smooth.

Agreed. This is all that 20 minutes could offer me.
This isn't rocket science. Give it a try. Lets see what you guys can come up with...

the method works - you have proved that. Of course there is a problem if you can see the sky in the renderings...
I really wish that you could execute a simple script in Studio an make use of the fantastic physical sky in a daylight timelapse....

Next Limit is all about simulation of the real thing. I think that the multilight technology could do it, but it would have to be faked.
I wonder if one could project light onto a hemisperical object to simulate sky perhaps?
