OctaneRender™ Standalone 3.00 alpha 4

[BorisGoreta]

I am getting this message on both render nodes occasionally. They had 8GB of RAM and then I upgraded them to 16GB RAM but still I get this message. Is this a memory leak ? Is 16 GB enough for 6GB GPU cards rendering 1080p only final render, no passes ? It surely is, the scene was less then 500 MB. Node is using 14GB so almost 16GB, tha tis why I get this message. Is this a memory leak ? How do I enable logging for the nodes ?

Sorry to be a PIA,

What is supposed to happen with Baking cam, is there a setting that is supposed to be applied, or a node that needs to be linked, that I could be missing?

I think the car has to have a proper UV map, then with baking camera it renders to this UV map.

Thank you Boris. That I may learn something - is an OBJ file typically exported without said UV map, as in some softs can export with (as part of the OBJ), while others do not?
Or, is there a node in Octane that in some parameter is looking for a separate file, exported along side an OBJ, like a .UVS file?

On the side, the pixelated clutter that the baking camera gives is great for making abstract art. Well done, OTOY!

It's possible that there is a memory leak, but I haven't seen it myself yet. If you could send us the scene I could have a look what's going on there.

Marcus,

I also got a system freeze when using the baking camera on 3 aplha4, I have all 12 GPU PCI 1x speed (6 of the 12 are on an Amfeltec 4-way cluster expansion).
Here is some additional info:

- If I use a lower resolution (ie 300 x 200), it goes right through to end, even 16,000 samples, no freeze
- if I use 1280 x 720, it freezes right at the end at about 15K samples
-if I use 3840 x 2160, it freezes right at beginning

My BSOD (blue screen of death) read this:
"A clock interrupt was not received on a secondary processor within the allocated time interval"

Hope this helps with something.

Welcome to the "freeze club" Notiusweb !
Seems that you have better USB risers for your Titan. It seems that it is worss with lower VRAM GPU (my 780Ti on USB riser get freeze very often , not only on the baking cam).
It also depends on resolution, I noticed the same issues.

Yes, I felt very frosty.
It actually reminds me of when I would run Octane Bench at very high overclocks and the Bench process freezes, but my GPUs are all still active and running fine after I close out the frozen Bench process. Although, the Bench script seems to be in somewhat of a sandboxed environment that does not lock up the whole system.

It may be connected to GPU VRam and PCI speed somehow, like there is an underlying capacity for it to happen, but it is dodged when you put less strain on a GPU's VRam, maybe.

Well, as cavemen would say,

MAKE FIX! ARRARRARARRRRRR!!!

I mean, I keep hitting my Titan Z's with a rock and it doesn't seem to help at all...

Okay, thanks to you and Boris for the help. Yey! Got it working!
What do you do with the texture once baked, is it something that is exported from Octane? (What type of file is it)
Also, (1) can the texture be sampled to any extent as it is being created (ie 1 - 16,000), and (2) can it collect/incorporate any medium (scattering, absorption) elements should they be passing through it geographically when rendered
THANKS
