Mesh vertex color with opacity doesn't render correctly

I have a open dome, and apply some mesh vertex colors to it with alpha. Yet it doesn’t show the inside.

Attached the dome, and 2 colored mesh as floor. As can be seen, the visualisatipn of the interior part of the dome doesn’t display those floor mesh . It does display the origin grid, so there is opacity. Any thoughts how to fix this?


display_mesh.gh (68.6 KB)

Also with material and breps. It is a setting I accidently activated?

Did you bake them? (The upper two are baked, the lower ones look similar to yours, they’re Gh previews)

I need it in grasshopper

I guess that’s a “no”…

Grasshopper draws preview geometry - you’re going to have to bake it or run your render from GH

Have you tried turning off the Ground Plane in your Rhino Viewport @crz_06 ?

Sometimes I’ve noticed odd overlap/visibility issues with certain GH previews and Ground Plane being active in Rendered style display modes
