Hi all!

I just re-installed the last version of Rhino 6 to solve this issue but did not work.

I’m assuming that’s the default mesh sphere correct? Radius=10, origin (0,0,0) and all that?

If that Rendered display mode you’re in? Shaded, Wireframe, …?

but happens with the other renderers too

Thanks, I logged a new item under RH-49915.

@tiralinies does it still happen after disabling the third-party plug-ins and Rhino restart?

Thank you very much!

I’ll follow the discussion

Did not

you mean all Grasshopper plugins?

( I wish I don0t have to do that… hopefully)

@DavidRutten is there any way to start grasshopper without loading any external components? This would help eliminate any possibility that something we didn’t write is interfering.

Sort of. You can run the LoadGrasshopperOneByOne command and then say “no” to all plugins.

@tiralinies can you restart Rhino/Grasshopper and try David’s LoadGrasshopperOneByOne command that he describes above? This will help us eliminate an possibility that an external component is somehow causing this effect.

I did as you and David suggested and loaded Grasshopper with the inhouse pluguins and now the shader is fine, and now opened a fully loaded Grasshopper (with all the pluguins) and the shader is working fine again…

I will let you know if the problem persists or re-appear (and try to figure out why that happened)

many thanks for the help

Same happened here. This is the ghosted view on Rhino. I have already Restore to defaults but nothing happens. Any suggestion?


Looks pretty much like driver issue, here a recent thread with similar looking issue. See if suggestions here help:
