An error I get now when using denoiser, wow these last 2 builds are packed with new awesome errors. Win10, pre-latest studio drivers, 2x 4090s.
Also it says "denosier", even the log window writes with errors.

By default I have denoising turned on on both GPUs, maybe that's the reason, shouldn't be I guess. I'll try to disable denoiser for one of them

Yes, please try with one GPU and let us know. We aren't getting that error nor your crash on the other thread.
This may also be a core issue too, but to know for sure or fix it we need to first reliably reproduce the error and crashes you are getting.

Turned off the denoiser for 1 GPU and still get the error occasionally.

Does everyone get this error when starting up?
but the octane works fine
although this window is not at all pleasant to see (

20.0.590 is the latest build for Octane. Shouldn't really run it with 20.0.625

Hello,

Trying to render Deep Image and get a fail on the farm with :

GUI equivalent shows : Using Windows and Linux on this build. I noticed a Deep Image fix in earlier builds but it seems to not work in this build. I'll test a few more work arounds to see what can be done.

Hi Renbry,

Thanks for the info, are you getting the same issue with 2023.1.2.2?
viewtopic.php?f=102&t=83227

Apologies - I meant to do a follow up.

I didn't realise I needed to have Deep Image enabled on the Render Target. I'm new to Deep in Octane.
I guess the error popup could help clarify that Deep isn't enabled in the Render Target whereas it just say's it's 'not on' which confused me when I was playing in the ROP.

Thanks!
Matt Hermans

Hello again,

We're having some unexpected issues with this build in the ROP's image path not seeming to 'compute' the path from variables we're using in traditional Houdini fashion -

Our Image File prefix is : "X:/ElectricLensCo/SPS/JT24/Houdini/render/Shot_`padzero(2,ch("/obj/Settings/shot"))`/v`ch("/obj/Settings/version")`/Shot_`padzero(2,ch("/obj/Settings/shot"))`_v`ch("/obj/Settings/version")`.$F4.exr"

which parses to :
X:/ElectricLensCo/SPS/JT24/Houdini/render/Shot_04/v1/Shot_04_v1.0480.exr
(in Houdini GUI)

However once on Deadline it's as if the ROP isn't parsing those variables and attempting to write down an image to a garbled prefix as follows :

2024-03-28 12:05:42: 0: STDOUT: 12:05:42 INFOR: [save image] -------- Saving the EXR "X:/ElectricLensCo/SPS/JT24/Houdini/render/Shot_/vch(/obj/Settings/version)/Shot_padzero(2,ch(/obj/Settings/shot))_vch(/obj/Settings/version).0001.exr" file

I haven't seen this behaviour before. Of course Octane's ROP works with a plain string as default; but we're trying to exploit a shot based workflow and pull variables in.

Thanks,
Matt Hermans
