Paint holes creating hole but still showing ground texture

Unity Engine

Using HDRP unity 2019.4.3 or 2019.4.4 (edit also 2020) when I use terrain tools to paint a hole it cuts the hole (player/physics falls through it) but the ground texture stays. Anyone know a way to fix this?

Added a video to show what is happening. Anyone have a fix for this?

This also a problem with 2019.4.12f1 (standard renderer) and others
If you bake the navmesh, it has holes in it.
Just doesn’t show them, which is annoying!

Hi! Could either of you provide explicit steps to reproduce this? That would be greatly appreciated. I can then make a bug report from that.

I’m still having this issue while trying to build a golf simulator in Unity 2019.3.9, standard render pipeline. I’ve used the Terrain Tools “paint holes” to remove the terrain in the unity scene where I need golf holes. I’ve imported a textured piece of geo from Maya to place under the hole, with a golfball-sized hole sculpted in to the geo.

But when I run the simulator, even though the collider is gone from the terrain where the hole is, it continues to texture the tiling grass texture over the hole-geo we inserted. You can sink a ball, but you can’t see the hole, because it is covered by the terrain texture even though there is no terrain there to support it.

Looked into an issue where Terrain Holes would show up in editor but not in build in Unity 2020.2/.3 HDRP (Collider etc. was fine, only visual). After a long time searching I found the checkbox “Terrain Hole” in HD Render Pipeline Asset > Rendering. Toggling this on fixed my issue (Default is off. For build time, apparently?).
Maybe related, maybe not. Maybe it can help someone in the future save some time searching (Closest I could find was this thread. Not much out there for Terrain Holes). Couldn’t reproduce the editor bug, sorry.

Broken - 2020 but I’m on the built in renderer - perhaps it’s never gonna get fixed!? Or…

If I enable “Draw Instanced” in terrain settings, the holes render but all my textures disappear. This is frustrating.

I found that if you disable the hole compression in the terrain settings it works.
