Does rendering in WIP have a memory leak?


I’m running some moderate architectural renders, and a number of the recent renders will get to around 96-99% completion before I get a notification (pictured) that my system has run out of memory. In particular, it shows that RhinoWIP is using over 130 GB of memory. Is this a bug? Is it my computer? Are there settings that I can optimize?

I appreciate any insights!

Hi, thanks for reporting!

We created this: I will try to reproduce the issue today.



Thanks for following up! Interested to see what you find.

This leak should be plugged in the latest RhinoWIP. Thanks again for reporting this!


Amazing, thanks for getting to the bottom of it!
