A.N.T Landscape displayed as black when operator is updated

Short description of error
Whenever changing a value in the A.N.T Landscape Operator, the mesh is displayed pure black. The display mode - solid, LookDev or rendered doesn't matter. Switching to edit mode and back resolves the issue.

The weirdest thing: I tried if it also happens in Cycles rendered mode (it doesn't), but when you switch to Cycles while the operator is active and then change a value, it switches back to Eevee and is black again.

Exact steps for others to reproduce the error

  • Add a Landscape
  • change the preset or update any value in the operator



Event Timeline

hi, seems my was fix is inadequate, issue is clearly seen with eevee drawing flat shading making the object appear non descript. toggle edit mode fixes and restores smooth shading to it's normal "look", however, not sure if this is Blender bug or addon bug. I will investigate further.

i do have the same behavior in EEVEE and Cycles. in both the default shading goes flat black

hi, I can confirm this bug.
To reproduce: Add a landscape mesh, change any setting and mesh is drawn flat.
To workaround I've gone through and made shade smooth off by default everywhere but the issue still exists if you use smooth shading. I'm not going to commit this "fix" as it resolves nothing.
Open to suggestions.

hi, no real fix here, I first disabled the smooth_mesh as default but it still errors when enabling in the ui. I then removed (commented out) the smooth toggle from the operator ui. The Smooth toggle is still available in the Create Tab > Landscape Main Panel and works with the Regenerate button. I also discovered an unreported bug with the Create at Cursor toggle, This has been disabled in the ui also.
Lowing priority as the issue could be solved properly at a later time. Thanks.
