Finally I had the time to render some crops and take some screenshots of the production scene I was talking about when commenting about Displacement Artifacts.
Here I´m attaching screenshots of the Facade geometry in 3 versions: the Original Geometry coming from Rhino, that same object with a Subdivide Modifier (Delaunay mode) applied, and a new object Re-Exported from Rhino with higher tessellation. Then you can check the crop render of that facade for each version, in 2 different Displacment qualities (ScreenSize=1.2 and ScreenSize=0.5) to check if quality affects this issue.
To my surprise, I was wrong, and with subdivision, the artifacts are getting more noticeable, instead of less. And, as you may see, the re-exported version of the facade, has more Displacement artifacts than the original geometry. Another weird thing is that, in the higher Displacement quality versions, artifacts are more noticeable (not sure if this is related to some kind Moire effect?).
Now I´m a bit lost here, if anyone can give some tips in how to improve the geometry, or what things to avoid, to make these kind of artifacts less noticeable, that would be welcome. How do you deal with these kind of surfaces in your proyects?
Thanks in advance
