Editor hangs as soon as a kDecal shares a scene with a terrain

[besttof]

Whenever a kDecal is placed in a scene that contains a terrain, or when a terrain is created in a scene where kDecals are present, the editor hangs almost instantly. Sadly, no useful data is logged in the editor log.

Unity 2019.3f6 macOS

kDecal revision: 493ce6d

Relevant packages in use:

"com.unity.device-simulator": "2.0.0-preview",
"com.unity.render-pipelines.universal": "7.2.0",
"com.unity.shadergraph": "7.2.0",
"com.unity.terrain-tools": "3.0.1-preview",

Issue replicated using:

• Unity 2019.3.7f1
• URP 7.1.8

If the terrain or decal are disabled in scene the Editor works fine. As soon as both are enabled the Editor crashes.

Unity 2020.1.0b12 here. Also tested with some different terrain shaders and unlit decal.
Maybe it isn't adapted to terrain yet, sadly, there is no results searching for "terrain" on this repository.

Any updates on this issue would be greatly appreciated!

This is kind of a weird problem, if you disable the decal culling, Unity will not crash any more. Seems like a bug when doing decal culling with Terrain.
