Displacement smooth

[scratch33]

Hi,

I have some problems with displacement.

Why do I have this "pixelisation effect"???
I use a 16 bit png then tiff 4096x4096 image to displace a plane. I have tryed to add more geometry, augmented subpatch, smooth on, But nothing, result is always like this.

Any suggestion? thanks

This is unfortunately damn near unavoidable, your only option is to increase the "level of detail" in the displacement node.

Edit: Also, the poly count of your geometry does not matter, which is what makes octane displacement wonderfully powerful, keep your ground plane a single polygon. If your geometry curves, however, you will have seams at polygon edges.

Is the displacement image covering a very large area like 200m x 200m?
You might need to cut the area in smaller areas.

Hi,

Thanks for reply.

My map is 4096x4096 and I use 4096x4096 level of detail.
Level detail is drived by the resolution. but what I don't understand is why we can't smooth the polygon without adding any detail.

Builtdown, my object is 16mx16m.

Is there any tips on what format, what resolution, or other advice to have a better result in displacement?
I have tried to import megascan maps and I can't do any close up view without having but results.
I don't understand Where I'm wrong.

Thanks

To have a better resolution you can use up to 8k texture maps (Level of detail 8192) and enable the Box or Gaussian Filtering, but well, if you take a really close up view, finally you are going to see this pixelation effect because this is how Octane works.

Thanks,

If the mesh is curved turn on smoothing to avoid the seems.
