OTOY Forums

I am getting crashes at different frames during rendering, but no crashes playing my project through the IPR. Below is my system information, crash log, and some things I have tried to fix it:

- turning off async save
- not rendering to mplayer
- using file cache on all nodes
- recreating the ROP node

If this is not enough, I can wrap up the project file and send it. The crash log is identical each time. Thanks in advance!

Hmm, the log seems to come from H18.0.408, but the loaded plugin is HoudiniOctane_18.5.462_vr.dll. This is going to be a problem for sure. Please check your houdini.env or packages config file to be sure that both Houdini and the plugin versions match. Using the ${HOUDINI_VERSION} tag in the config files usually helps to avoid these problems.

Thanks,
