I suppose the title really suggests what I’m trying to do but to explain it more I’m making a terrain digging tool and recently found that workspace.Terrain:Union_Async() exists but doesn’t give any documentation about it neither does it seem to work like union operations on base parts.
How can I do this? I’ve seen this been made before so it’s not exactly impossible.
It’s not supported. You can’t use it.
I recommend you to use this plugin.

Things like explosions in games have been able to union terrain.
The UnionOperation combines parts together into a single solid model.
As I said, you can’t create UnionOperation from Terrain.
If you want the ability to modify terrain, read about ReadVoxels and WriteVoxels.
There are also several functions that are also used in terrain editor you can access: FillBall, FillBlock, FillCylinder, FillRegion and FillWedge.
Explosions have a hard coded ability to deform terrain.
