Hello, Houdini heightmap tiled export has seams between the sublevels.

Here are my export settings:


Here are the results:


If anyone has any advice let me know, it looks like some kind of approximation issue since they almost line up correctly.

Hi,

That's caused by the HF_Output node not having the option to export tiles with an overlap.
(we're already aware of that issue).

A workaround would be to wrap your Heightfield in an HDA and use the Houdini Engine plugin to bring your terrain to Unreal.

Hi,

This has been fixed in today's daily build (17.0.395).

The HF_Output node now has an additional parameter when exporting tiles, called “Tile Overlap”, it allows tiles to share a given amount of points on their border.

For game engines export (and specifically for unreal), you'll want to set the overlap to (1,1).
(also make sure that the tile size you export matches unreal's landscape size requirements).

Why is my version 17.5.229 HF output tile imported into UE4 still has gaps?
