@Enrico : Welcome to Madland ! For my own, sometimes the alembic file is generated after each frame... sometines only after the last one and sometimes there is no alembic file at all in the folder...and I get server crashes too...

@Jimstar : 2 PM in your Box with files.

Three words to mention here:
- Network
- Cache
- Future


Don't forget that Blender plugin is not just plain plugin as all other plugins are, it is extremely complicated client-server system. You have two distinct applications communicating over TCP connection to each other (sending commands, transferring data, etc...).
So, you should not only ask the server to create alembic file for you (how do you mean network server is able to create the file on your local computer?), you should somehow get it from the server back and store on local computer after the export is done.

@Jimstar : PM in you box... Sorry, same behaviour... Console Screen shot and Dump file provided.

VERY VERY BAD NEWS : I am typing these lines on my old pentium used for internet and simple office work : Just after posting the first line of this post, the power switched off and it was the total black out. I switched off all things which were ON and went out to the general switch and saw that the plugs line was off. I put it ON, and came back inside : My workstation is dead ! I Can't start the Cubix box without the signal of the workstation, so I don't know if the Cubix and the Graphic cards inside are safe. I Hope that my HDD are safe... The power supply of the workstation is probably dead ! I don't know if the workstation is the cause of the trouble, or if it is an overload of the general power lines around here... I will not be able to test anymore... and work... for a while !

I will open the workstation case later...

05:26... I fear that I will not sleep at all.

Ok I can live with that for now, so let's count on the future

What you mean by "can live with that for now"?.. What do you not like?
Perhaps here is some misunderstanding: it right now already takes into account the future and works that way which it will work in future, after the server will be able to be placed on remote computer. It will not change from this point of view... And for you there is absolutely no difference that the server stores the cache of alembic file somewhere: the only important thing for you is where Blender stores this final output file which it gets from server.

Does anyone still get a jittery camera when they export the alembic file?
Everything is fine in Blender, but my rendered animation starts smooth and gets very shaky at the end.
I'm using Octane 1.52 which is supposed to fix an alembic import bug. I will post there too.

@Kavorka : I encountered the problem some time ago, and the recent version fixed it. But a very recent test shown a jitter problem again, but as my camera had very special constraints with frame delay and a vertex parenting to a surface used as a guide, I have to investigate more because in this special case it could be due to my camera rig.

@Jimstar ! My computer is saved. I have changed my power supply unit to a Corsair 750W monorail PSU fortunately available in my town, tested my hard disks on an other machine and remounted and everything works ! Pffffieww !

This is for the good news. I had not well seen last time, and there is enough room for the external pipes of the GTX 480. So as I have now enough power to feed it, I have replaced my GTX 260 (Compute capability 1.3) by the GTX 480 (2.0)... And sadly it changes nothing for the use with the plugin : Octane server still crashes every first time and works when reloaded without closing Blender.

After mounting the GTX 480, when starting the machine for the first time, Windows 7 Pro did its usual bad thing : it tried (and failed) to use a default bad driver instead of the right one already installed and I had to reinstall the driver.

I had a very short hope as the first time I tried with the new PSU (but still with the GTX 260, as I did the thing very carefuly step by step) because it worked ONE UNIQUE TIME. And crashed again at each following attempt. So I decided to mount the GTX 480 with the poor result you know...

Sorry again for the bad news...

Hi - there a 2 issues:

1st: Specialy for german people. Using TexturImages with "Ä Ö Ü" inside the filename will not be loaded
2nd: It seems that the offset for environment-images will not be changable? Till now i have to rotate the camera+objects to get an outher background-position.

Greets and HAPPY EASTERN!

I know they fixed an alembic import bug recently, but maybe there is something they missed, or an export bug with the plugin? It always happens at the same spot, even if I export less of the animation. Its only when I keyframe the rotation.

Hmmm, now I am getting the same problem when I try to recreate the camera movement with a target that is moving...
