Alpha channel for geometry colors is ignored
I tried to add transparency to the surfaces of a geometry.
Solid faces
gmsh.option.set_number("Geometry.SurfaceType", 2)
and tried both of these here
gmsh.model.set_color(gmsh.model.getEntities(2), 0, 0, 255, a=220, recursive=True)
gmsh.option.set_color("Geometry.Color.Surfaces", 128, 128, 128, 128)
The color is correctly stored with a alpha channel, but is ignored in the viewer.
It would be nice to add this.
