As a Roblox developer, it is currently too hard to check if a region is empty. Which is pretty strange since workspace has a function but only pertain to instances.
As you know, A region is required to ReadVoxels, as well as WriteVoxels. While reading voxels may not be detrimental to performance, checking materials to see if the region is empty is. It’s kind of weird to think that with Regions having a prominent usage. And there being a function to check if a region is empty bounding box wise. That the actual usage towards Terrain has fell behind.
Adding functionality that lets you check if a region is empty will be beneficial because Filling a Region with a material is faster than writing voxels in a region (confidently assumed not factually proven). And by having this feature one will be able to fill regions that hasn’t already been filled. Or check if a region is filled with water… and so on… and so forth.
