Houdini problem with rendering to render view.

I am having a problem trying to render a very simple scene to the Render View pannel. It renders to MPlay with out a problem. It gets stuck at the generating scene part.

Houdini 17.0.353 and appropriate Arnold plugin.

Thanks,

Steve

Hi,

I am still experiencing the same problem even when I have updated to the latest Arnold builds and the Houdini 17.0.459 build.

Any ideas where to look for a solution?

Thank you,

Steve

Then everything works for me up until the "render starts" part for the render view. I works ok for MPlay and rendering an output file.

Any suggestions?

Thank you and have a great holiday season,

Steve

Hi, I have updated to the latest build .416 and the problem still occurs I can see where the ASS is written out to:

"00:00:00 795MB | [ass] writing scene to c:\users\steven\appdata\local\temp\houdini_temp\htoa_Steven\30064_c92a8f92-0d41-4b18-bece-69a6584d9b4b.ass (mask=0xFFFF) ... 00:00:00 795MB | [ass] wrote 8208 bytes, 9 nodes in 0:00.00 00:00:00 795MB | 00:00:00 795MB | releasing resources"

As soon as the file is written it is removed. Not sure if that is the correct action. I did make sure the the write only flag on the file was removed. Same behavior happened afterwards.

That's normal (the ass file being removed). The ass file is deleted after HtoA reads it back in for rendering. The sequence is:

  • Houdini exports the ass file
  • HtoA (hick.exe) reads in the ass file
  • ass file removed (cleaned up)
  • render starts

Thank you, maybe the next up date to the latest production build will fix the problem.

Have a nice day,

Steve

Sorry, I can't tell why it's not working

All I can see is that there's no communication happening after the ass file is exported and read back in.

  • Normally Houdini exports the scene to ASS
  • Then HtoA reads the ASS file, does the render, and sends it back to Houdini.

But in this case, nothing is sent back, and given that there's no Arnold log, it looks like the render doesn't happen. But there's nothing in the Process Monitor log that tells what the problem is.

That is what happens when you get old, you can no longer depend on your mouse skills.

Hopefully I completed the process correctly. Here is a link to the file:

Let me know if the information is usefull or if I messed it up and I will redo it.

Thanks,

Steve

@Steven Shook Oops, that's the help file for Process Monitor. The log will be a .PML file.

Can you get a Process Monitor log? Then we can check whether something weird is going on, and maybe even spot the problem.

  1. Download processmonitor from https://docs.microsoft.com/en-us/sysinternals/downloads/procmon and unzip it somewhere
  2. Run Procmon.exe from where you unzipped it
  3. Start capturing events
  4. In Houdini, render to the Render View
  5. After the render doesn't happen, stop the capture in Process Monitor, then go to File -> Save. Zip up the log file and put somewhere where I can get it.

thanks
