Material Tab and thumbnail preview being extremely slow

[Iyang_Huang (Ian Hwang)]

The material tab is extremely slow. When I hover mouse over an material it takes almost a second or 2 for the material to highlight. Disabling material thumbnail preview helps a little bit but still very very slow. Didn’t have this issue in Rhino 7… Does anyone else have this issue?

Could you run the systemInfo command in command line of Rhino and post the result?

Thanks for your information, could you try to update to Rhino 8.13 ?
https://www.rhino3d.com/download/rhino-for-windows/8/latest/

I noticed that your device has two graphic cards, could you try to make Rhino running on Nvidia display card ?

Rhino doesn't use newly installed Graphics Card NVidia GTX 1050

'Never tried messing with that. Firstly, when doing system work, it’s always more relaxing and safe to do it after having done a full backup. Anyway. This is how I set I Rhino on the old “Mobile Workstation.” After installing the latest nVidia drivers, and rebooting, I right click on the desktop, I choose “Nvidia Control Panel.” There are two modes of managing the 3D settings. At some point, it might be best to put it on the expert settings, it might read different, but you get the idea. I ju…

Hi Jessesn,

1. The problem with slow material tab & thumbnails has been persistive since the first service release. I don’t think updating will resolve it because this issue is never specifically addressed.

2. I am positive Rhino is running on Nvidia GPU. The Rhino handles complex model very well if without material tab turned on.

[jessesn (Jessesn Chen)]

Sorry for the inconvenience. Could you pls help record a video about this issue? it seems that I haven’t found a similar problem on my side. Thanks.

Hi Iyang -

@Iyang_Huang

I don’t think updating will resolve it because this issue is never specifically addressed.

I think this issue is being discussed here:

Material Dialogue and List

Thank you for the test model. I tested with the following combination. EnableGL = True EnablePreview = True EnablePreviewCache = False And now I can also see a lag when opening the dropdown. When the Cache is set to false, then we do not cache the previews and they get always regenerated. Can you make one more test for me. How does the dropdown work when both of these are set to false and then restart Rhino? EnableGL = False EnablePreview = False.

@Iyang_Huang Can you take a screenshot of the material editor?

[Iyang_Huang (Ian Hwang)]

hi Wim, Thanks for the reply. I have tried the settings suggested in this thread.
The problem persists with the EnableGL = False EnablePreview = False.

I also think, this only poses a temporary makeover - we still need the preview back down the road. It was available in the previous builds of Rhino.

Hi Max, thanks for the reply. Please see here:

Both your Intel and Nvidia drivers are out of date by enough to affect current Rhino versions. You might want to update those as well. If you update to the current release of Rhino then McNeel can be absolutely sure they are diagnosing and attempting to fix a problem that still exists.

[maxsoder (Max Söderström)]

@Iyang_Huang Thanks for the video. Can you share the model?

[Iyang_Huang (Ian Hwang)]

absolutely. what’s the best way to share the file with you?

[maxsoder (Max Söderström)]

Large and/ or confidential models can be uploaded here.

But if it is small enough (I do not remember the limit) and not confidential, then one can attach it to this thread.

[Iyang_Huang (Ian Hwang)]

thanks! it’s uploaded.

[maxsoder (Max Söderström)]

@Iyang_Huang I am wondering if the problem is the tinyicons (the blue balls). If you unassign all the materials does the hovering of the mouse get quicker. Also the viewport selection?

If this is the problem then I have a fix for it.

[Iyang_Huang (Ian Hwang)]

HI Max, unfortunately, unassigning material does not help with the issue.

[maxsoder (Max Söderström)]

Thank you for the information.

[maxsoder (Max Söderström)]

Thank you for the model. What if you load protect the Enscape plugin?

In Plug-ins locate Enscape and click the Enabled column. Then restart Rhino. Does this impact speed?

One other thing. Is there a difference if you switch from list mode to tree view?
