Hi, I’m currently evaluating the demo versions of Rhino 7 to see if I should update from my version 5 license. I’m encountering a strange issue where if I only render on one GPU, everything works, but if I enable both my GPUs, I get a black screen, although the line below the viewport shows some activity.
It does not matter which GPU is active, either one alone renders fine
The same system works great with Redshift, Blender and other GPU renderers.
My setup is using a GTX 1080 TI and a RTX 2080 TI. 64 GB RAM, Windows 8.1 x64 all with latest updates and drivers…
Rhino version is (7.0.20314.3001, 09.11.2020).
I have Cycles set to CUDA in Preferences.
Thanks for any pointers!
Please run the Rhino “SystemInfo” command and post the results.
This will tell us what Rhino sees for system resources.
Hm, when exiting Rhino 7 I was offered an update which I accepted. But after installing it, I can’t start it anymore but get an error that “Rhino requires a license to run. Rhino will now exit”. Huh - I had 87 days left on my trial?
Not a very encouraging start I have to say…
Ok, this is officially dumb - the updater inside the demo version installs the non-demo version… which then of course doesn’t work.
Either disable the updater in the demo or update to the latest demo please!
Okay, uninstalled Rhino 7, reinstalled Rhino 7…

Looks good to me?
Multi-device rendering is currently broken. It is on my list ( RH-57576 Ensure multi-device works ).
Adding this thread to the YT item so you’ll get notified when it is back up and running.
Ok, so I can at least stop trying …
Will I be able to update my evaluation copy somehow? Or am I stuck with the version I downloaded?
Whenever we release 7.1 you’ll be able to use that, should still be within the evaluation period. I don’t know if I’ll be able to fix it for 7.1, but working hard through my bug list.
Well, I just had the experience of my evaluation copy downloading a non-evaluation version update, so I’m not sure how this system is supposed to work, update wise…?
The installer is the same for full and evaluation. It is the license key that matters
I have no idea how it’s supposed to work.
I only know I downloaded and installed the demo version, when it offered me an update I accepted and after installing that, I could no longer start Rhino 7 with above error message.
When I re-installed the older demo version I downloaded first, it worked again.
If that is not what should happen, I’d either need an explanation, or it’s a bug.
What I would have expected is, that the update would install and use the demo license that the initial installation obviously somehow found/used. That’s what pretty much every other software I’ve ever tried did, if the demo wasn’t explicitly a separate file/version.
But after some more demoing, I’m not sure I’ll update my version 5. Somehow I’d have hoped that two versions later somebody would have done something about the clunky 1990 GUI and the archaic workflow.
Especially with SDS modelling, the whole command centred thinking is just in the way.
So my current plan would be to continue doing SDS modelling in Blender and only turn to Rhino for conversion if a client really needs NURBS models and update Rhino on demand in that case.
Cycles in Rhino, the other thing I was curious about, feels very dumbed down from what Cycles in Blender can do, may be okay for very simple things, but everything is so clicky and longwinded and simplified to death and absolutely not helped by the crappy GUI.
Without nodes, it’s a really crippled thing, like a horse with the legs cut off…
Also, Version 7 doesn’t seem very mature for a release version, I mean dual GPU rendering isn’t exactly bleeding edge? I use it for ages…?
But yeah, doesn’t matter too much, it seems Rhino still isn’t really for me and probably will always stay in the “use if I have to” category.
Cheers and all the best,
Just came back to this since I actually may have a job that requires Rhino.
When looking at the bug tracker, this feature has been moved now to 7.5. Outch!
My demo expired already of course…
This is quite disappointing.
