Rhino 6 issues

Hi,

I’ve been using Rhino for about 4 years now and started with Rhino 5 which worked great overall and if there was a problem, I could understand its cause and how to eventually fix it. Ever since the update to 6, however, I’ve been having a LOT of problems. I use it with V-Ray to render and the issues keep piling up.

I contacted Chaosgroup and I want to give detailed reports of what bugs and issues I’m encountering and I would like to do the same with Rhino. Please let me know what format I can use for this, what information you need (system, versions, screenshots, etc.) and what is the best channel for this communication.

Since I’m both a Rhino and V-Ray user and my company distributes both these products, I’m directly interested in knowing if these issues are going to get resolved or how to fix them for my clients.

I am not listing all the bugs in this post right now, because I’m documenting them as we speak and I’d like some info so that I can sort out the Rhino from the V-Ray ones and report them in the right places. I have searched for solutions online for most, but I found the answers usually unreliable.

I am writing this message because, for the second time this month, I opened up a model file only to find it unusable and damaged. The program was closed properly and I carefully saved the file beforehand. The first time this happened I simply loaded the backup and all was fine, but this time Rhino would become unresponsive when opening the model and the backup was unusable as well. I had to go through a loop of importing the model data from the backup into a new file to make it work. This is just one of the problems that have completely halted my work. I have worked a lot with Rhino 5, with a lot of plugins and something like this never happened.

I’m looking forward to finding out how I can help fix these issues.

Regards,
Alexandru Vasile

Hi Alexandru - the first thing to do is disable VRay and see if the problems, whatever they are, persist. If you run the SystemInfo command in Rhino and paste the results here, that would also be helpful.

Hi Pascal,

Thanks for your reply. I have been looking into this in the last few days and it seems most instability issues happen because of V-Ray.

Two remain only in Rhino though. The one I described in my initial message, which I can’t reproduce by choice and which happened without me using V-Ray, (although it was installed the second time it occured) and a sluggishness that occurs often when I move elements.

It almost always happens when copy-moving items with the Gumball, but it can also pop up when I’m doing something as simple as placing curve control points. I have seen this is a common issue and I tried (almost) all the fixes I could find here on the forum or that show up in a Google search. My video drivers are updated, so is Windows, my power plan is properly configured and there are no background processes that could slow Rhino down. I tried changing both Rhino and nVidia settings and nothing made a difference.

I’m posting my SystemInfo below. I have reverted most settings back to their original state if they didn’t change anything, but perhaps I’m missing something?

Hi Alexandru - thanks-

This has also been associated with some versions of VRay. From what I can see your system looks fine - the only thing that sticks out at all is the presence of VRay. Do you have the latest VRay? Have you contacted them? We have reports from the past couple of months about this sort of sluggishness.

-Pascal

Hi Pascal,

I tested it out and here is what happened:

I uninstalled V-Ray. Rhino started performing better. There was slightly more lag when using Gumball to create object duplicates than when moving objects, but overall the movements were smooth.

I installed VisualARQ 2.0 and then I noticed something I didn’t see before. The viewports were working perfectly when maximized, but the problem was there when all 4 were visible. This time though, the movement wasn’t sluggish, but choppy and lagging behind my cursor. Drawing a polyline, the control points would be placed with some lag after my click.
I did not manage to reach the initial state of Rhino again to check if this was caused by VisualARQ or not. From this point on, uninstalling plugins did nothing for performance.
I uninstalled VisualARQ and Rhino performance remained poor. I cleared remaining registries with CCleaner.

This is how sysinfo looked at this point:

I installed V-Ray 3.6 again. This time the downgrade in performance was obvious outright. The cursor movements were not choppy anymore but completely sluggish and lagging behind my mouse and clicks by up to 10+ seconds as if they were buffered. This was in a completely empty scene. With one viewport maximized the movements were significantly better, but still not ok.

I then uninstalled V-Ray again, relaunched Rhino and nothing changed. It was just as slow as before. I reinstalled Rhino, cleared the registry with CCleaner, but nothing improved. I restarted my computer, uninstalled Rhino again, deleted everything left over by Rhino, VisualARQ and V-Ray in %appdata% local and roaming, in program data and every registry I could find with REGEDIT. Checked for strays with CCleaner. Restarted my computer. Reinstalled Rhino 6. This time it looked like a fresh install. Performance was still abysmal as if I had never uninstalled V-Ray.

This is my Sysinfo now:

As a comparison, I still have Rhino 5 installed. When installing V-Ray 3.6 on it the performance dropped, but upon uninstall it recovered without having to do anything else. I loaded a scene up with geometry and it only slowed down as expected, when gumball moving or copying very high amounts of geometry. Even then though, drawing a polyline would perform normally.

Even with no addons, Rhino 6 was not as fluid as Rhino 5 is for me (with an empty scene, before uninstalling addons started changing nothing). With V-Ray installed, Rhino 5 will be at most 2 control points behind my clicks unlike Rhino 6 which can buffer up to some 15. Performance dip in Rhino 5 will also be identical regardless if the viewport is maximized or all 4 are in view.

This entire problem is tied to cursor movement. Any other changes I do to models via command line, parameters, history, etc seem unaffected.

I am in contact with Chaosgroup and will take this further with them, but I need to find out everything I can. As I initially said, I am talking to a client right now and need to find a fix and a cause for these issues to help him out properly.

Thank you for taking the time to read all of this, it’s much appreciated!

Alex

Thank you for the link, David, but the problem described there is not the same as mine, nor are the solutions.
I have never encountered a problem using CCleaner to fix and maintain dozens of systems over many years.

This is exclusively a Rhino 6 issue, as Rhino 5 (and every other program installed on my computer) is working just fine with everything I did.

Hello again and Happy New Year!

I would have liked to start off 2019 with better news, but I am still working on fixing the Rhino 6 install on my computer.

Could you suggest a way to perform a completely clean Rhino 6 reinstall without having to format my computer and reinstall Windows? Is there such a way?

Best regards,
Alexandru!

I think this is everything.

  1. Uninstall Rhino using the Programs and Features tool in Windows’ Control Panel
  2. Using Windows File Explorer, delete any license related files in:
    1. C:\ProgramData\McNeel\Rhinoceros\6.0
    2. C:\Users[YOUR LOGIN]L\AppData\Roaming\McNeel\Rhinoceros\6.0
  3. Delete any shared plug-ins in:
    1. C:\Program Files\Common Files\McNeel\Rhinoceros\6.0
  4. Delete the Rhino installer engine:
    1. C:\Program Files\McNeel\Rhino Installer Engine
  5. Using REGEDIT, delete the following hives:
    1. Computer\HKEY_LOCAL_MACHINE\SOFTWARE\McNeel\Rhinoceros\6.0
    2. Computer\HKEY_CURRENT_USER\Software\McNeel\Rhinoceros\6.0
    3. Computer\HKEY_CURRENT_USER\Software\McNeel\McNeelUpdate\6
  6. Restart Windows

Plug-ins might be in
C:\Program Files\Rhino 6 - I would delete that whole folder.

I’ve deleted all of those files and registries and reinstalled Rhino 6.

I’ve followed all instructions, but the problem persisted. I was going to post a recording of my issue but now it affects Rhino 5 as well so I’m going to do a fresh Windows install since I can’t pinpoint the issue anymore.

Thank you for all the help. I’ll post an update here with my situation, hopefully a fresh system will work now.

All the best,
Alexandru Vasile
