[image] New Display Mode called Concept in Rhino 9 WIP I wonder if they got inspiration from “share your favorite display modes”. It looks really good!! Yeah, I wonder … But I don’t get why they show all the tangent edges, though. And I guess it’s a bit buggy still (there’s no meshes in this …

[image] eobet: EDIT: Actually, no it’s a new Beta bug… here’s my Technicolor viewport mode on that same object (which has worse, grainy shading in V9 than V8 sadly): [image] @eobet do you see this on all objects? If it is object specific, can you send that object?

All objects all files for me. Again, done a lot of factory resetting and OptionsMigrate, so settings should be clean/transferred from V8.

I will try to reproduce this by loading your display setting in Rhino 8 and then an option migrate.

@eobet I can’t reproduce this here. As for the grainy shadows, this can be fixed by increasing the skylight slider from 0 to 3-4 pls run _SystemInfo and post back the results. And from Rhino BETA, if you can run OptionsExport and send the .rhs to me I can at least verify if it something in the opt…

systeminfo.txt (2.2 KB) rhs in upload. [image] Gijs de Zwart: grainy shadows, this can be fixed by increasing the skylight slider from 0 to 3-4 Any way to turn off ambient occlusion? In V8, the technical shadow mode had more of a toon shader look which suited it better, imo.

hi @eobet I think I found the cause of what you are seeing, can you confirm you were using (rotated) blocks? RH-97590 Messed up monochrome shading with transformed blocks

Yes, seems to be fixed in latest beta thanks. But again, how do I turn the ambient occlusion completely off? This is supposed to be a technical view mode which looks very clean in V8: [Screenshot 2026-09-17 103716] Yet this ugly in V9: [Screenshot 2026-09-17 103559] I don’t want the ambient …

You need to use “scene lighting” and remove/switchoff the skylight.

[image] norbert_geelen: You need to use “scene lighting” and remove/switchoff the skylight. I could not get this to work, and even with “no lighting” I still see the ambient occlusion so I strongly suspect that it is a separate effect decoupled from any lighting but I can’t find the button to…
