Missing anti-aliasing in terrain edit mode?

Development Rendering

We just noticed that while in terrain edit mode, antialiasing is apparently disabled. Is this intended?

I included a video but sadly I don’t think the issue is really visible because of heavy video compression.

Steps to Reproduce
Press shift-2 to edit terrain. Notice heavy aliasing issues.

Hello,

This behavior is intended. You can control it from the “Project Settings → Engine → Landscape → Configuration → Disable Temporal Anti Aliasing in Landscape Mode”.

For more information, please see “FEditorViewportClient::Draw(…)” from EditorViewportClient.cpp, and search for the comment “Landscape brushes don’t play well with TAA”.

Please let us know if this helps.
