Change color backface/material in shaded or rendered display mode c#

Rhino Developer

Hi all,

I’m trying to programmatically set the backface color of al objects. So far I’v found this setting with which I seem to be able to toggle the ability to set the color. But I cant find the property to also set the color.
On the rhinocommon page I can find this property:

public Guid BackFaceMaterialId {get|set}

However this doesn’t seem to be exposed at the moment.

Would this be the correct property to set color and material? Or is there another method?

kind regards Reinder

Hi @r.weenink,

Are you just looking to change the backface color of a display mode, or something else?

Hi Dale,

Exactly the backface color setting in your picture.

Hi @r.weenink,

I see this is not possible in RhinoCommon yet. I’ve logged a request.

Hi Dan,

Thanks for the message.

Which version is this?

@r.weenink - none of the above.

This has been implemented in Rhino 8.8. I don’t see a pre-release 8.8 NuGet package yet.
