i believe there is an issue with how the memory is handled....
i'm finding that when my project is ready to be rendered,  before rendering I save...shut down the program,  then restart it just to render -   this is to flush out the memory that has all the undo data.   I also notice by simply leaving a project open for a long time without use -  ie taking a break and picking things up a few hours later -  also leaves the program unstable - so restarting the program is my current fix for all things crashes - at the very least to help isolate whatever other issues may be present - such as a potentially bad mesh from a prop i imported or a corrupt jpg.

Is anyone experiencing a memory crash while using iRay? This started happening for me after the 1.4 update. Sometimes saving the project as new helps but recently it has stopped helping.

I have reference images posted here: https://www.reallusion.com/FeedBackTracker/Issue/iRay-render-unstable-crashes-at-random-points

If anyone knows a work around or can tell me how to correct this issue it will be greatly appreciated as I have a project which is in the final stage but keep having iRay issues.

The only way I was able to prevent this crashing was by removing hidden particle objects and rendering at 720p down from 1080p.
