Invert & Hide Extremely Slow After Last Update

After updating to Version 6 SR5 (6.5.18155.13161, 04.06.2018) it started to take long time to invert selection and hide objects. Is there any way to fix this?

Hello - I have not heard this before - is this the case with any file or just some?


Hi Pascal,
I checked again. This seems to be an issue with each file I work with. Even with very small files. It takes approximately 2 seconds for the task to complete while I’m sure it was much faster before the update. I don’t think it’s an hardware issue. I installed a plug-in recently but this was after the issue started to occur. I also recently get black viewport every time I start. I get 3 of 4 viewports blacked as seen in the screenshot. They function normally after I click on a viewport and zoom in or out. I am also attaching my hardware list, I am using a Quadro K2200. Thank you for your response. Please let me know if I can do something to help diagnosing the issue.

Can you run the command SystemInfo inside Rhino and post the results?

Well, I guess the first thing I would do is try updating the video driver, it’s from early 2016…

I did update it to the latest version and it didn’t help. Although when I run Rhino in safe mode everything is smooth again in wireframe.

Hmm, that does indeed seem like video problems… But I really don’t know how to proceed from here. @DavidEranen ?

@cyzc Have you checked directly at NVIDIA website for a newer version? I think for there is a newer one:

Windows can’t find the newest version sometimes.

Seems like it’s the Rhino Resurf plug in that is causing the issue, which I guess is written for Rhino 5. I disabled it and now it’s back to normal.

OK - thanks for letting us know.


same problem now on my computer… RH6 64bit and latest SR, Windows 7 64bit.
Takes extremely long if i use _invert _hide command
I run RH in save mode without all plugins and this works fine with the invert, hide
So it must be a plugin which causes this problem…
Activated one by one of my plugins to find out which is the “bad boy”

Finally looks like it’s the “VRay” Plugin - latest Version.


Have you contacted ChaosGroup to let them know?

No, not yet now, i can do this, if this is the best way…

It is the only way (-;

Does “Isolate” just do the same steps as invert hide or is it a different code?

I would think that it is the same code, just putting stuff into another container. @pascal?

Hi all - Isolate is using Invert plus the ‘hide buckets’ provided by the -Hide and -Show commands, but behind the scenes…


Any news on this?
I just got the same behaviour. Isolate takes a long time to think on some large files. But it used to be fast before.

I just tried it with 125k spheres.
Isolate and Unisolate seemed reasonably snappy to me.
It seems a bit faster than Invert+Hide and Show.

I just tested a fix this week for Isolate that effects the V6 Mac WIP, so the code did get touched.
