Sun animation?

[SATtva]

And if I manage to get a good grasp of it, I will have a very good reason to buy new hardware to be able to render much faster , otherwise I will be old before my 250 frames of a complete sunrise->sunset animation are ready

If you're just going to look at the sky without not much objects in the scene, it won't take much time to render an animation even on the old hardware. Sky lightsource converges very quickly, a couple of minutes on a quadcore CPU in FullHD. If you need real geometry in the scene, then, depending on the scene, you could probably get a decent result even with a Directlight integrator or a Path integrator with 3-4 bounce depth, try them first.

Well actually I'd like to use it for an architectural simulation.

So once I get it working, I'll probably make tests at lower resolutions, with low bounce depth as you suggest. Maybe I'll use an idle server at work to render overnight

[Edit] I couldn't wait, so I fired up Blender during lunch break and I got it working! Yeah, you're DA man SATtva
(for those reading the thread, one thing that was not mentionned: grab latest LuxBlend from mercurial repository in order to see the new feature in the Cam/Env tab)

Btw, my tests were done at work on windows platform, but when I tried to do it at home on my linux, I was unable to launch luxblend anymore.
I always got a script error. In the console, I found the following:

I remember having read something about this issue (sha and hashlib) in the forum, but couldn't find it with the search engine. I also tried to update my python packages (still 2.6.2, but installed python-dev too), with no luck.

Could someone help? I'm a bit stuck for the moment (except to revert to older version without this nice new sun IPO keyframing option)

Odd, this should still work in 2.6.2. Anyway, I've pushed an update to resolve your problem.

Hmm. I still have the issue. Although the line errors now differ, and I get a smaller chunk of scrambled characters

sorry to bother...

[SATtva]

Ok, another try. Test out the latest commit.

[MaRo]

Works! Still get a deprecation warning and some garbage in the console, but luxblend runs.


Thanks a bunch!
