Thank you for your continued support.
When creating a nearly vertical cliff in a Landscape, artifacts appear in the distance field. To be specific, sharp, pointed shapes emerge in the area above the cliff.
To confirm the issue, take the following steps:
(1) Create a new level.
(2) Add a Landscape to the created level.
(3) Create a steep cliff using the Landscape tool.
(4) Create a new material. Multiply the DistanceFieldGradient node by 100. Connect it to the emissive output.
(5) Apply the created material to a mesh such as a Cube. Check the distance field around the cliff in the level.
I have attached screenshots for confirming the issue.
The first image shows the appearance of the created level.
The second image shows that pillar-like artifacts appear in the distance field near the cliff.
The third image shows no issue occurs with a cylindrical shaped static mesh actor, resulting in correct rendering.
If there is any possible workaround to avoid this issue, please let me know.
Thank you.
