Hi @maxsoder sorry I was out of office for the thanksgiving holiday. I have asked internally and installing the tools are not permitted unfortunately. Would you please schedule the inspection with @aidan.newsome please?
I appreciate all the help and assistance along the way!
Hi Aidan, it’s good to know another user with the same issue. Would you please coordinate with Max for the inspection? it requires some tools that I am unable to install on my office laptop.
I would love to stay updated on this matter to learn about you solution in the end.
Thanks!
We are going to try this with @Elias_Brulin tomorrow. Fingers crossed…
Any luck?
I am pretty curious about what you have found too.
No, not yet. We are still investigating this.
Could not Rhino be working on the preview–before you bring the material tab to the service?
Last time I checked, the PBR Reflection Polish and Roughness–were still backwards in respect to one another.
I tried to reproduce the problem with the model you gave, but I am unable to do it. I have had two meetings with users and we have identified two cases that can cause the slowness.
Case1: Textures on a server.
Are the textures on a server? Can you test how the performance is if you use textures that are on the local computer. Textures that are on the same computer as Rhino is running on.
Case2: No rendered previews.
Maybe this is another case we do not yet know about?
EDIT: I can now reproduce the problem.
Can confirm that this is not due to textures on a server - slowness happens even when all textures are local.
Did you ensure that the 3dm file references the local textures, and none of the textures on the server?
How about case2? Does you rendered previews work? There is a link to another thread that explains how one can test this?
Has there been any update on this?
Yes, we have made fixes that are in v.8.16. v8.16 is planned to be released on February, but I can send you a DM if you would like to test this before that.
I would love to try it if possible. happy new year!!
would like to share an issue that seems related to this thread.
When creating custom materials using an external renderer, not only does the material tab preview become slow, but the undo command also becomes significantly slower.
However, if only Rhino materials are created, the speed of the undo command is not affected.
Opening the same file in Rhino 7 does not cause the undo slowdown issue, so I believe it may be connected to the problem discussed in this thread.
For reference, here’s a brief system environment:
hi Aidan, following up to see if you have this problem resolved on your end?
it is truly unfortunate that I have not been able to use Rhino in render view any more after upgrading to Rhino8. The display performance in render view is like 1/10 of Rhino 7. Really confused about how newer and supposedly better software actually has heavily reduced performance. what happened…?
Hey Ian. Sorry, I’m not on here much. It was solved in one of the updates, sometime in June, if I recall correctly.
