Are you using a library that wasn't packed into the blend-file? (oscLimbs, uprightLimb?)

Currently nothing to render.

We're keeping the old (the ones with id <3000) sessions around for figuring out what caused them to fail and eventually fix the issue and render them or abort them with an explanation.

Currently the farm does not support multiple outputs per frame without using OpenEXR multilayer outputs when using splitframe rendering. You were the first one to try it and it has been added to the todo-list as a feature request.
The 3D stereo in splitframe rendering mode outputs 2 segments per workunit and this does not work with the current stitcher which can only stitch workunits with one segment per workunit.

Since this session requires splitframe rendering your options are:
- Manually download and stitch the frames in an image editor or Blender
- Red/green stereo
- OpenEXR multilayer
- Render left then right

If you do the first one then you can use this link:
https://burp.renderfarming.net/img_handler.php?session=3371&frame=1&part=1&type=direct
Modify frame from 1 to 2, part from 1 to 120

Looks like something went wrong with the tiling in this session. Looking into it

BURP is a lot more efficient if you upload animations rather than single frames that cannot be split because of node postprocessing

This session seems to be clocking in at around 28.8GB of RAM or so without the Blender UI, so it may be a bit slow because it will run on only a very limited number of hosts.

At the moment this is also very close to the limit of what we will even try to render. Hopefully within less than a year we will be able to update the scene checks etc. to more easily support very large sessions up to around 32GB of RAM.

The physics system for this session references data that was not included in the .blend-file. This may or may not be a problem for the render - we'll give it a shot

Working on switching to LetsEncrypt as CA - expect some issues with HTTPS for a few days.

[Edit:] Ended up taking just 48 mins to set up. Hopefully no issues

It is likely that there will be an OpenCL client at some point - at the moment the Cycles rendering engine has been maturing in that area quite quickly. Just recently there was a massive rewrite sponsored by AMD of the Cycles rendering kernel. The results look very promising

There's a single, very lonely, Mac OSX CUDA workunit out there now. Extremely dangerous, may attak at any time, we must deal with it.

The scheduler is set up to send it to the cuda_fermi plan class on x86_64-apple-darwin. This may or may not be how BOINC refers to CUDA on Mac.

Another quick update on this one - the problem was deeper in the connection between the Payday script and the backend system than originally expected. The BOINC server page's statistics was only a symptom of the underlying cause.

The script talks to the backend through a special connection. It turns out that the connection can stall if enough data has been sent through it without any answers going back in the other direction. The status page updating could cause a delay in answers and hence cause a stall. Tweaking the timing settings for the connection seems to have almost, but not quite, eliminated the stalls.

The old workunits have been moved to long term storage.

Presently we cannot confirm or deny anything about the Mexico wall project

Since April 2004 we have been under a Non-Disclosure Agreement with Space Exploration Technologies Corporation, better known as SpaceX. In 2017, yesterday in fact with the completion of the rocket re-launch live stream, the contract ran out and we can now finally talk publically about what has been going on behind the scenes all this time as we move forward into an open collaboration with SpaceX on their upcoming missions.

Space is hard, rocket science in particular is very hard. In 2004, just a few years after the SpaceX company was founded, they approached us with the problems they were facing. It had become clear that it was simply too dificult to complete the rockets and development that was required for NASA launches and instead the proposal was to simply render very convincing computer generated 3D graphics instead.
This is where BURP comes in. In 2004 it was very difficult to do these kinds of convincing animations - they initially tried using just normal office computers with simplified night-time visualizations but people on Twitter had become aware that many of the early "launches" seemed to occour at night. Quite quickly the rendering was offloaded onto BURP and we set up a front to look like a rendering service where people could get their Blender animations rendered - when in fact we were rendering SpaceX launches for their "live" streams.

Now that the NDA contract has run out we don't have to wait until the live stream starts in order to publicly show what is being rendered.

Elon Dusk, CEO of SpaceX had the following comment:
BURP is awesome. Now that it has grown so much we expect to be able to render missions to Mars way before 2019, there is nowhere we cannot appear to be going.


Also, when SpaceX eventually catches up with the reasearch for real actual rockets, part of the agreement is that BURP will get to be amongst the very first customers to launch its servers into space. That should make the workunits a lot lighter.

If you missed yesterday's show be sure to check out the "live" stream recording.

This session got stuck in an unfortunate bug in the upload handler and was recently recovered.

This session and 2766 have both been rejected because we do not yet support rendering physics systems from .zip-files.

Switching this to best-effort mode. Credit at next Payday run.

Some of these units are extremely slow while others are insanely fast. If it takes much longer it will probably have to be switched to "best effort"-mode.

OpenEXR support is currently an experimental feature available on request - you must request it in the session description, otherwise your session will be stored as PNG.
Do you want me to clone this session as OpenEXR?

This scene was already rendered, the result is available in Session 3264
The session was rejected.

Texture "black studio.exr" referenced as environment texture is missing from the .blend - did you remember to pack it before uploading?
This session has been rejected.
