Weird Black line in Glass Render

Get Help

Hello, I am trying to render a patio door, which has double plane glass, and in the final render, using PT, it has this weird black line, and also off reflection. It is also there in the viewport display. What could be the issue? Is it a bug?

Hi @nicolaslvigier

Could you please check a few things:

  1. If you temporarily hide one of the glass planes, does the black line disappear?
  2. Are you using the default D5 glass material or a custom/imported material?
  3. Does this issue appear only in this specific file, or does it also happen in a new test scene?
  4. Does the issue also appear in the real-time viewport?
