OctaneRender™ for Blender 1.27 - 3.1 beta Win [OBSOLETE]

[radiant]

I seem to be having a problem that i have had for the past 3 versions,
When ever i am rendering an animation or rendering in general,
Octane server will decide to close, thus me, having to re open it, "rendering" the animation useless.

Is there a way to work around this problem yet?

The same thing happens to me as well. If you save your animation out as individual frames (PNG) and then you can use the video sequence editor to output the frames to an animation file. Also if the server crashes you can just start the render on the frame that it was processing on.

As near as I can tell there is a memory usage error that the Octane devs haven't found yet. This can happen when a memory pointer starts changing memory locations that it shouldn't. So it either overwrites the program itself, or it tries to write to memory outside of the block of memory given to the program by the OS. If you run the server from a cmd window what error does it report?

Thanks for reports.
Please, post here the content of Blender console messages after the server gets crashed. It may help in catching the reason.

Hi JimStar,

Here is the errors I get...

Blender console:

Code: Select all

...

Here is the Octane Server console:

Code: Select all

jason@gemong bin$ ./OctaneServer 
ERROR: Program executed illegal instruction.. terminating
Terminated

I had to kill the server, that is the Terminated line above. Have you tried to run the server through valgrind? I did try it but because the OctaneServer that I have doesn't have the symbols in the executable it doesn't give me very good error messages. It does complain a lot though. Sometimes the server will sigfault. Standalone crashes on me too, so maybe the problem is in the code they both share?

Thank you very much for the info.
Just one thing to mention: it is the wrong thread for this bugreport. As not only it is about Linux version of plugin, but even Octane engine and plugin versions are absolutely different in current Linux plugin release, so the reasons are rather absolutely different.
Moreover, as I already wrote earlier - especially Linux version of Octane SDK has some fluctuating bug which we so far can't reproduce on our side in debug sessions (it seems it is bound to network usage somehow)... But after I will return from vacation I will spend some effort especially to catch this Linux SDK bug.

Regarding these last Windows releases - there may be absolutely different reason of crashes mentioned here, as these 3.x versions were refactored very much to use new Octane engine, so there may be some little bugs as the consequence of this big rework (bugs which don't exist in current Linux version)...
So, it may be helpful if some Windows users who has exactly this version of plugin installed, would post here the messages of Blender console after the crash...

Octane server will decide to close

Same here, for me octane server will stop after 20 frames give or take 3 frames. I'm glad radiant posted this.

Thanks JimStar,

Sorry about that, I was hoping they were at least similar. It's just frustrating when Octane crashes all the time.

Re: Blender octane server crash. (During animation renders)

100 frame cube animation
Png-100 samples

The console displays each saved file then I get a windows 7 msg box "octaneserver.exe has stopped working" with a menu item "close the program"

As soon as octane server is closed the console displays "octane: network send error" and that line just repeats until blender is closed.

I changed the output type to jpg and 2x the frames rendered than with png

It's rare that my system crashes and have yet to complete a animation render, so my first question would be has anyone completed an animation render session?

Hi!
Can´t render scenes with many many particles.
I made them renderable using objects.
Talting about > 30.000 particles. Blender stops in the "transfering"-process...that will never end.

I know - cycles is different, but it can render that particle-objects in a few seconds. So it seems that not my GPU is the problem (3GB RAM). Am i right?
