Hi octane team,

I wrote post here http://render.otoy.com/forum/viewtopic.php?f=27&t=41227 but nobody from Octane team reply me(except Karba, with question which version I´m using). This problem comes with every 2.xx versions.

It´s not only my problem with net rendering. For me it is unusable when I can´t use more then 1 slave. This is very big issue! Could you anybody give me comment?!

I´m waiting 11 days, but nobody care for thi BIG PROBLEM. I heave buy this version mostly for this future, but I can´t use it. I´m going to feel cheated.

Thank you
Jan

The devs are looking into this.

Thank you Goldorak. I know that you have hard work, if you will have some news about this problem, give me know please.

We can't reproduce your problem here in the current version. There was a bug in version 2.01, that got fixed with 2.02, where slave results were not used, when the plugin was fetching an HDR result from the slaves. But as I said it got fixed. So could you please be more specific and tell us

a) What exactly is the problem? Does the saving hang or do you lose samples? If the latter, how do you know that you lose samples - could you show some image or something?
b) What is the configuration you are using? (OS, GPUs of master and slaves)
c) Does it happen all the time and if yes, what are the exact steps to reproduce the problem?
d) Do you have a particular scene that causes this issues and if yes, could you please send it to us or upload it (encrypted if you want) to some file share provider (like mega.co.nz)?

To be able to fix problems we must be able to understand and reproduce it. A message "doesn't work" doesn't help. We always need the configuration, an exact description of the problem and a way to reproduce it (example scene, step-by-step instructions, ...).

Yes I remember that problem in 2.01. I have render 60 sec animation without problems in version 2.02. But the scene was not too big.
This problem comes with 3-4 GB scenes.
This problem is very strange and it has no rules for me. Maybe size of scenes only.

a)Saving is ok but I lose samples. At first I thought, that only slaves crashed during saving but result is ok, because it was computed over night and I had no knowledge about samples. Then I noticed, that I lose samples in short render time where it was clearly to see.

b)W7,
Master-Titan, 680 for screen, 1000W power supply
1.slave-Titan, 480 for screen. 1200W power supply
2.slave-4x Titan, 2x 1500W power supply.

using 1. slave only, it is mostly ok, but not every time.
using 2. slave only, it is mostly crashed, but sometimes after shorter render time it is ok.
using 1. and 2. together, lose samples mostly from 2. slave, sometimes from both, sometimes is ok (mostly in shorter render time)

So this is everything what I have notice. I´m just artist not pc expert and I hope that this will help you. I´m sorry I had no time to make test images. Tomorrow I´m going to holiday, I will be back in one week. http://render.otoy.com/forum/viewtopic.php?f=27&t=41227 here are other user with same problem which can help you. When I will be back I have no problem with sending some scene or make test images.


All the best

Ok, thanks. The problem is that your slaves crash. They shouldn't. When a slave crashes you lose the samples calculated by it. The same way you lose the samples of a failed GPU. This is currently a limitation and we plan to remove it in the future, but that will require some work we didn't have time to do yet. So for now, it is important that the slaves don't crash.

If it's a hardware problem, we can't do much on our side, but probably you for example by monitoring the temperature. It may also be worth to figure out if one particular Titan is causing these issues, by disabling GPUs one by -one.

If it's a software problem we can try to find and fix it (see also http://render.otoy.com/forum/viewtopic. ... 68#p196168). As a first step, please place this file into the directory where the octane_slave.exe is located: The next time the slave will be launched by the daemon, it will do more (net render specific) logging and also write the log into a file octane_log.txt. You should place octane_log_flags.txt in the directory of the master, too. This way we can see what is happening on the master side. Please be aware that the file can only be create if Octane is installed outside of the programs folder or when run as administrator, as otherwise Octane wouldn't have permissions to create the log file (see http://render.otoy.com/forum/viewtopic. ... 68#p196168 for information).

thank you, I´m back. I will try it.

Jan
