Terrain:GetMaterialColor

@SuperDave6502 Are there any plans to make Terrain:ReadVoxels() and (maybe) Terrain:WriteVoxels() compatible with parallel? Currently they mutex lock, which means they can be used in parallel, but only one thread at a time can use them, ruining the point of using them in parallel :

`Terrain:ReadVoxels()` should not mutex lock in parallel luau

Currently, as of 5/23/23, the Terrain:ReadVoxels() API sets a mutex lock when any actor threads call it, so that only one thread at a time can get voxels from Workspace.Terrain. This makes it impossible to read & serialize massive amounts of terrain in parallel through the use of actor instances. If Roblox were to allow ReadVoxels() to be called at the same time from multiple threads instead of mutex-locking (a write-lock only with no read-lock), it would allow developers to serialize huge amou…
