Hi, I have 2 questions regarding the Rhino 8 material dialogue. Problem: everytime I bring up this list from layer panel, I need to wait 5 seconds for the thumbnail to come up and refresh. This “delay” effects the productivity quite negatively. Is there a way in the advanced settings that I cou…

Good to know that this issue will be looked at and optimized. I found that having these combinations make the dropdown a bit faster. [image] EnableGL = True EnablePreview = True EnablePreviewCache = True Maybe you could verify with my attached file above. Good to know that the dropdown image …

We rewrote the UI for v8 so we know there will be things that need to be fixed. What happens if you turn off the EnableGLPreview? Does that make it faster? Clearly here is a thing that needs to be fixed/optimised, I think that it would be good to add a way to define the size of the dropdown 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 y…

[image] Max Söderström: 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. With this combination and Rhino restarted, there is completely no lag with the dropdown at all. The trad…

Thank you for the information. Was the EnablePreviewCache initially set to false? The dropdown should eventually get faster when it caches more and more previews and in the end they should all be cached, but that can take some time. Are you using Rhino Render as the renderer? There is a setting th…

[image] Max Söderström: The downside is that the rendered previews sharpness is not as good as with 150 samples. But typically 10 or even 5 samples will give more than enough info to determine the behavior of the material.

my material tab slowness persists with all the suggestions above. Didn’t have this issue for Rhino 7. It’s new after upgrading to 8 and have been bugged by it since SR1… any other settings you can suggest?

Chiming in, In over 12 years of using Rhino and with my latest PCs being ca 15 times as fast as 10 years ago 2 things have never been as slow as they are now (Running Rhino 8 on both a Laptop and a Tower with the same issues and it’s not about performance): Layer Panel has gotten slow and is lagg…

I had a similar suspicion that the culprit to the slowness/UI lag is due to material preview rendering. I brought it up in another thread but received a denial from @dale [image] Rhino 8 Lag layer expansion/collapse Rhino for Windows No. The slowness comes from Eto/WPF. …

I think there are several factors involved that cause the slowness. I am myself trying to solve these issues for the material panel (not looking at layers panel as others have better knowledge about it) and try to find fixes if possible. As there are probably several factors causing these issues th…
