HipHeight is labeled as read-only, but after testing in Roblox Studio I was able to modify it both through a script and the command bar just fine. Is this an outdated or incorrect annotation by chance?
I see, fields that are read-only but not parallelly is labeled Read Only, not Read Parallel. I still find the tooltip for Read Parallel is a bit misleading:
This property is read-only and is safe to read in unsynchronized threads. Attempting to write to it causes an error.
I’d suggest adding “In parallel” as a prefix for clarity.
