Just picking up Houdini for the first time. Quite daunting, but so far good fun. I'm just playing around with a basic shelf pyro sim with a few tweaks, but I'm having trouble when it comes to rendering that out to disk.
I'm working with 100 frames, and I managed maybe 3 or 4 successful renders before hitting issues. Oddly rendering to Mplay will cook and render the whole sim without issue.
It fails frame 34 each time - I'm not getting any explicit failure warning (that I know of). It just looks like it's taking a really long time to render, though it's definitely dead. Middle clicking the Mantra out node gives me a very long list of things I don't understand ops:
What should be my first port of call? Initially I was rendering to the network - I've tried local with no success. Why would it be able to render to Mplay but not to disk?
If it helps, it's a 16 core machine with 64gb ram on Windows 7.
what you can do is to mike your hip file public so the community can check whats wrong. if you can't share your file reduce it to a minimum where you can make it public and the bug still shows up.
it's much simpler to analyse the file then to guess… :-)
Here you go I just made a fresh project as I'm sure in the time I've been poking around the other project I could have inadvertently broken something, but rendering to disk still fails on frame 19 - Yet it will render fully in MPlay.
tested the scene here and there is no mantra rop or any output rop i can find. anyway i simply added a mantra rop and rendered frame 1-20 with no problems here. no fail on frame 19. sorry.
Thanks for checking Physalis, strange that its throwing up problems at random frames. My last sim, albeit with different parameters, failed rendering on frame 54, so I don't think there's anything special about frame 19. I could actually get that sim to finish in Mplay either.
Physalis Doudini, how can I get the access to the TEXT of node errors like you've juste posted? Thank you for the response!
On your mantra rop under Statistics you can put: Verbose Level to 3 I also switch Dont capture render output and check alfred style progress
If you started Houdini from a Terminal, you will see all the output there. From there you can copy/paste it. Otherwise there should be a popup window with the output.

So I made a fresh scene, kept it basic - A sphere animating along an axis for 120 frames. I was able to render this twice without issue.
Added one stage of complexity - Animating the sphere on 2 axis. Now it crashes. Sorry for large chunk of text. I'm investigating the segmentation fault now but posting it up just in case anyone has an aha! moment.

Will do. I did pop onto support but the first thing I saw was about apprentice users getting help with install and licensing but that was it, so I just left it!
Oddly, I downloaded a scene file for a particle sim made in regular Houdini. Rendered 270 frames without a hiccup; far more strenuous than anything I've tried so far. So perhaps either something being created in Houdini Apprentice or just on my machine.
ops: 
I just made a fresh project as I'm sure in the time I've been poking around the other project I could have inadvertently broken something, but rendering to disk still fails on frame 19 - Yet it will render fully in MPlay.
