The promised preview has some faulty frames and it will take a little while to figure out what caused the frames to be faulty. Stay tuned.

What's the status with allowing other renders alongside the BBB Sunflower units? Doesn't look like more than one or two have gone through since Sunflower began.

It's fine as long as they are made in Blender 2.4x - the current client on the farm. Work is being done on switching to Blender 2.6x clients but there is some licensing issues keeping things stalled for the time being. Recent development seems to suggest that the licensing issue is being resolved (at least an agreement has been reached), but no final confirmation as of yet.

Furthermore the Sunflower event is being extended into 2012 (obviously) to finish it properly. There's still a lot of work to do.

I just ordered 8 GB of RAM for my desktop, so hopefully I can get a piece of the pie and help it along some. It was a little hard justifying the purchase, since DDR2 is not as cheap as DDR3, and I had though about assembling a new system sometime in the near future. Guess I'll hold off on that for a while.

Yeah - hard-drive prices are also pretty high right now and going down quickly so it's probably a good idea to wait with an entirely new system at least for the time being.

RAM arrived today and installed without a hitch; I'm a bit late to the party, but am downloading my first Sunflower WU right now.

A little news-update on Sunflower:
Things are generally progressing quite fine.

1)
We may have found ourselves a sponsor! This is great news for the Sunflower project because things were starting to get a little expensive (mostly due to external consultants and the hard-drive prices going up last year).
I'll post more when I know more, exciting stuff!

2)
Jan Morgenstern will be creating a new soundtrack for the credits scene so that it can be extended to also include the names of everyone involved in the BBB3D&4K version as well as those people who were involved in the original version. Check out his page for some of the other work he has done for the Blender Foundation and other organizations.
Also be sure to select how your name should look in the credits.

3)
It is likely that we may be looking at a combined release on the Internet (free) as well as on physical media (BluRay for the 1080p60fps etc. and HDDs for RAW, not for free though, there would be some cost on producing these) around Xmas 2012 if there is enough interest. Would you guys be interested in physical media releases?

Would depend on the size of the movie I think. If it's that much that it fits a BluRay I probably would prefer that way, because my net connection is (still) way too lame for downloading.

Well, the size would depend on which version of it you would like.

The standard HD version is probably going to be around a few hundred megabytes but since there are several standards for 3D and super-HD content (and certainly 3D super-HD content) there's going to be 5-10 different versions so that as many people as possible can play it with their favorite equipment without having to convert it.
The BluRay standard itself does not support content above 1080p as far as I understand, so that would be the video encoded to the playable part of the disc and all the other versions would be stored on the filesystem part of the disk - to be played through a computer or a special player.

[Edit:] The highest resolution stereo version (that is 2x4k at 60fps) would be rather large - several gigabytes. The raw version of it would not even fit a BluRay - that one is going to be around 2TB and would be distributed on a harddrive. Those two versions would probably only be useful for demo-, cinema-grade or really high-end consumer equipment, though.

The slow sessions are starting now. Things will be a bit different for those as compared to the normal ones, for one thing the deadlines will be greatly extended to match the increased complexity of these scenes and we will experiment with lower than usual level of initial replication.

Update on other stuff:
The sponsoring thing I talked about earlier, although somewhat messy at first, seems to now be moving in the right direction. More about this next week.

I've talked to Ton (Blender Foundation) about the possibility of a BluRay or DVD release of the 3D/high-res version. He was quite positive that if we do decide to make one, and it is of comparable quality to the original DVD, then it could be traded through the Blender web shop.
This is quite nice news since I'm not certain I would be able to personally manage all the packing, shipping and international trade stuff - they naturally have a great deal of experience in this area.
Later, a kind of register-your-interest-list will probably be set up to see if it would be worthwhile or whether people simply prefer to download it for free over the magical Interwebz.

Any revised estimates as to how much longer the Sunflower project will take? Wouldn't it have made more sense to have the "slow" sessions started first?

I recently arrived back from a nice vacation in Germany - I'll have an update ready next weekend with some status on the Sunflower project and whether it is still on track for a December release.

With regard to the slow sessions: When Sunflower started I had about 10% of the scenes ready and tested and expected to be able to convert and push the remaining scenes to the farm in a relatively short amount of time (less than 1 year) - I was wrong, it took much more work to fix all the scenes. Unfortunately none of those first scenes included slow or buggy scenes, so I was unaware about them until much further into the project. Even then, the hope was that it was a bug in Blender causing this (it probably is) and that the cause of this bug could be found and fixed. A lot of work has gone into isolating the issue and it seems to be related to ambient occlusion calculations in high-detail scenes. However, turning down the quality of AO is dramatically lowering the quality of the output image. Trying to use different versions of Blender will render other portions of the scenes incorrectly. We're kinda stuck with rendering the scenes the slow way - and that is why they are last.

As promised a status update for the Sunflower project:

Pretty much all scenes have been converted into 3D and 60fps. There are some scene-related issues left to solve but they mostly revolve around one of three things:
1) The intro/credits scenes (see below)
2) Single-frame issues. Sometimes a series of 3 frames freak out and makes things fly around the scene. The reason this happens is that the BBB team assumed that the movie was ever only going to be displayed in 24 fps (a fair assumption really) and some of the objects act funny when their timeline is stretched to 60fps. I'm in the process of finding the issues and fixing them. This will result in some sessions with low frame count at some point.
3) Not everything has gone through quality assurance yet, so there may be some re-renders if stuff with issues is detected by the QA team.

With regards to (1) above there is some bad news. I worked with finish Studio Lumikuu and composer Jan Morgenstern to try to create a new title image (the old title image and other DVD art is not opensource) and a structure for an extended credit scene. Unfortunately the Blender Foundation vetoed the credits scene completely. The list of reasons for the rejection is long and fairly abstract and the way it was delivered was painful to me. I'll give the credits scene another rewrite and try it out on Ton again, maybe the time was just really bad last time... if things go haywire again it is likely that this part of the project will be crowd-sourced in some way (for instance through a competition).

A lot of people have requested a status page for the overall progress of the Sunflower project. It's alive!
Over the next week or so the remaining sessions will be added to the overview and more of the future plans will be included so that it easy to track overall progress. Most of the data is already available, but not connected - it takes a little while to manually make the links that cause data to pop up on the status page.
When we get closer to release it will also be possible to download the .blend files from that page.
Some of the numbers look somewhat funny (like 120% completed sessions). This will be explained in detail on the status page soon.

The weather here is really nice, so things may be moving a bit slowly for the rest of the month - blame the weather gods

Frames are still rendering at a good speed.
We seem to be missing the December "deadline" by one or two months at the current speed. There are still some complications with regard to the title screen, the credits section as well as potential sponsors - none of the problems look like showstoppers, fortunately.

And some more good news: The movie in its entirety has now been reviewed by the QA team and they survived to tell the tale! This means that it will be possible to actually view the movie without it causing severe brain injury, bleeding from the ears and instant blindness - that is certainly a great step forward for the Sunflower project.
They did have a few final comments that will be taken into consideration and are likely to cause some re-renders:


  • An out-of-focus leaf in the front left of the bird intro scene (A.01.03) is disturbing the 3D effect:

  • A branch above the head of the main character seems to go through his skull during animation in A.09.03:

  • ...And a few more. All in all the feedback was good.

How much longer do you think Sunflower will be rendering? I've been over at WCG chasing badges on a couple of short-lived projects, keeping three hosts from rendering. Hopefully, they'll be back on the job in a month or so.

No idea really - we still need the two 10.02 monster sessions, they are going to pull out some teeth because they are both slow and have more than 2000 frames.

I bet on a half up to another year.
Currently I'm on my last silver badge on PG, but then I'm back here also. Want to reach the 500k before the event ends. ;-)
I guess with the sessions who need readjusting credits I could have already over 400k.
