Small errors when baking displacement maps I am baking a simple displacement from several Bezier curves. The curves are beveled and set to full. Whenever I bake the displacement map, I get several small errors. Here is the baked .exr applied via a displace modifier to a heavily subdivided plane. Several of the baking errors are circled in the image below.


What is the cause of the errors? What can I do to get rid of them during the baking process? Because I can not edit the image externally with out compression artifacts.

The blend file, just open and press bake.
Looks like a baking bug to me.

Investigation shows the artifacts are already present in the .exr and the displace works as intended. I just subdivided a plane to 16.78M polys for 4096 texture and it showed the same result as you posted.

Artifacts in .exr:



Then I tried converting the curves into mesh, different curves resolutions and smoothings, normalized/unnormalized bakes but I always got black pixels at different random spots.

When I plug the raw bake into compositing nodes and inspect it it has artifacts, so it is not the exr.

The only solution that worked for me are smooth modifiers after the displacement, which is not really a solution.
