Large Files in Worksessions (still) Not Working

I have a large project in Rhino 8 that I’m attempting to use worksessions to manage. Not in order to collaborate with people but so that I can manage the file sizes of the individual drawings.

Rhino takes inordinately long to open <300mb files in a worksession but manages it. Rhino fails to open a 500ish mb file. I have left it running for over 15 minutes and it doesn’t get anywhere.

I’ve noticed quite a few other people have had other similar issues but I haven’t found a solution.

I couldn’t find a solution here also it doesn’t look like memory usage is the issue in my case.

In this case Rhino seems to be crashing. My Rhino does not crash it just seems to get stuck without making progress.

Hi Adam,

Is this on a networked location? Are there Vray/Cosmos materials involved ?

Here are instructions on how to create and send us a crash dump on a hung instance of Rhino.

Hi japhy,

I’m not working from a network drive. I am working from a Onedrive folder but all relevant folders and files are local. There are some Vray materials but nothing from Cosmos and the Vray materials that are there are basic generic materials.

Cheers, I’ll recreate the issue and create a dump file once I have a sec later in the week.
