I can't tell anything from the video.

Can you strip down the scene...is it just the one thing that crashes?

Also, if you start houdini from the command line, and change Log Verbosity to Debug and increase the Max Warnings to a high number, do you see anything else in the log?

I need to explain I have a sim fluid if my sim fluid is disabled I can render, if I activate my sim arnold crashes


I have already renderer my sim whit mantra, but now I need to render my boat whit arnold and put my sim in matte but in matte or alone Arnold crashes


and when I make a new geo node with a file cache loading my sim I have the same result


but I need to have the sim in matte for my final compositing in nuke

For Mac and Linux the command line is Terminal.


The Log Verbosity and Debug can be found in the Arnold ROP - Diagnostics

That looks like everything stopped during scene translation (when HtoA reads the Houdini scene and converts to Arnold data). Possibly on this object: /obj/guidedoceanlayerleopold_fluid_extended

How do I reproduce this? What do I create in Houdin? Or can you provide a simple scen that reproduced the problem?

Yes, it crashed on first render for me. I added a clean node with Remove Degenerate Primitives on and it rendered without any issues.

If this is crashing for a certain piece of geometry e.g. the fluid wake, can you please upload the file so that we can look at the fix?

Hello here is the problem on guided ocean layer if you put a file cache and load it arnold and houdini crashes


but if you dont do it you render time take more time with the file cache i save 2hrs


I edit the problem is not the cache file is the delete node if you made a cache without the delete node no problem
