Edges visible on backface depending on the aspect ratio of the geometry
Depending on the aspect ratio of the geometry, the edges on the backface of the geometry can be visible whereas the opacity is 1. But I don't think it is a problem of opacity, more a problem of edges vs aspect ratio. This issue is similar to #19723 (closed), but I am running on Paraview 5.8.1 RC1 and I have already observed the benefits of this fix for the representation in general (but not the issue reported here!).
- Source -> unstructured cell type -> apply
- Change the representation to surface with edges
- Select hex with a grid of 1 x 10 x 1000, apply. See the spurious edges on the blackface of the first picture
- Select hex with a grid of 1 x 10 x 10, apply. Everything looks ok, see the second picture.
