Hi again,
Ok, here a video that show the problem is normally not in Octane or Cycles, seems to be link with driver or cuda :

Hi Jim,
Well, this is not a bug but a problem I meet working with linked libraries. I often use linked libraries to include models in my scenes. I try to name objects to insure they are well individualized but it's not always the case and this could be a problem. For instance if I include two different libraries with in each one an object with the same data name and if I create instances with the scatter option, the Octane server consider all the objects as the same instantiated object, this is clearly due to the same data name. During the export of the objects to the Octane server, would it be possible to individualize the objects with the same data name when they come from different libraries ?
I hope to have been clear enough ...

Hi,
So I re-installed my computer with a driver before the last one, and Octane standalone seems working without problem but only one card load datas in memory.
After that, the driver 334.89 seems to resolve the lag and freeze bug (or blue screen for others ?). To be sure remove the old driver before install this one. Also, be carefull, the Nvidia Geforce experience forces you to install the last one driver and lock the nvidia Geforce experience panel if you not say "yes install the last one". If problem, kill the panel from Task manager

@MattRM : I have not explored your posts in details, but I think (I may be wrong) that if you display at the same time the render preview and the real render window, you are making your GPU doing two different tasks at the same time. it may be a cause of failure.
A second thing : I have read something in your posts about SLI optimisation... for Octane, SLI must be disabled ! GPUs have to be independent.

@ROUBAL :
I already turn off SLI and the lag is not during two different task, one time viewport, second time batch render (F12). No more problem since the driver was an old one. SLI was not really a problem with the old one driver, but always turn off my SLI. Here was just to test from where the problem came. For my two zotac GTX 670 4 Gb, it was the driver. But maybe, with the new driver, when you stop the viewport rendering, the server not turn it off, and that's why the problem appeared. but for the driver 334.89, with or without SLI and jumping from viewport rendering to batch rendering or just stop/start/stop/start the viewport rendering, no more long converting object or lags.

Hello there Jim, i think i found a bug, or im doing something wrong.
When i export a dissolve animation to alembic file and then open in octane, the materials go a bit crazy.
There are only 3 materials in blender file, and the alembic file has 3 nodes that I set with 3 different materials, but when you run the timeline in octane they change position, and new materials are displayed, when I cannot select them...
The easy way is to open the Octane file and see for yourself, I have attached both the ocs file and the .blend so you might take a look.
cheers

Visibility seems not to work (shadow and cube should be invisible).
Did I miss something ?
Kind regards

Hi,
You need to set your cube as "movable proxy". If as global, all the scene will be compiled as one geometry, so impossible to say "cube is not visible" because is the same global object. Need to restart the rendering to apply the new meshes compilation.

Hi Jim,
I'm facing a annoying problem, I'm trying to create a surrounding environment with trees. So I used scatter to be able to instantiate the required trees but it crashes. Well it works fine let's say with about 5 trees but as soon as I increase the amount of trees, Blender becomes uncontrollable as well as the system and I should restart the machine. In the task manager the memory seems to be used at only 75%.
Any idea ?

Enrico, I need a little more detailed description to be able to reproduce it.
Can you please describe step by step what should I do to reproduce and in what exact moment of these steps you get the crash?
