Houdini crash at saving file Octane 2018.1.0.3

[juanjgon]

What a weird issue! Can you please send me a new log again? I want to be sure that the crash happens always at the same point.

Thanks,

i've noticed 2 things :

rendering an exr : no crash
rendering a png : crash

i've tried rendering a simple scene : it renders
> but in the png format : the image looks buggy (vertical lines) see the jpg attached to this message.
> whereas for exr option the exr image rendered is right.

Here a two octane log

the one in exr format which is not crashing houdini
and the one with png which does crashing houdini.

Okay,



Render status ok, no crash :
EXR render : Pathtracing I 25 sples I Adaptive Sampling on I AI light on I Denoising on I Motion Blur on : camera MB, Objects MB, Lights MB, Deformation MB

I have enable the trail sops to compute velocity and it still renders.
EXR render : Pathtracing I 25 sples I Adaptive Sampling on I AI light on I Denoising on I Motion Blur on : camera MB, Objects MB, Lights MB, Deformation MB


then tried to up the samples (step by step.... i put more stuff into it to be sure)
EXR render : Pathtracing I 1000 sples I Adaptive Sampling on I AI light on I Denoising on I Motion Blur on : camera MB, Objects MB, Lights MB, Deformation MB

Ok. So Octane only crashes if you try to save a PNG file, right? One question, have you tried the latest build released this week?
viewtopic.php?f=102&t=70914

I ask because really I can't reproduce this problem here, and I don't have any other report about a problem like that. I wonder if the problem could even be related to the filename ... if the latest build still crashes, can you please check this filename?

Code: Select all

The image is rendering but not saving :
what does this means : External WM_DESTROY received for QWidgetWindow ?

I'm not sure. This is a Houdini warning. Currently the Octane plugin is not using Qt at all ...

Have you tried the latest plugin build, or changing the file name?

Thanks,

okay got no more errors now

the previous error was due to empty geo (a controller for the cam position), so adding a cube in it but disabling visibility resolves this.



BUT STILL, i don't know why but the file is not saved

18:14:02 INFOR: [save image] -------- Save image function enabled

the log files says the opposite, so i don't see what's the solution,

Thank you JaunJgon,

Please, changes the prefix filename. Perhaps somehow Octane has a problem with your current filename ... can you please try this one?

$HIP/render/test_$F4

seems like " $F4 " is not working : the image number is not implemented into final image file name
