Two minor areas to review over.
The rest looks good to me. 👍

It seems that this last adjusted line is not used... and the property found is not being assigned to anything.
Is there a reason to keep this line?

Purpose of this PR
@smitdylan2001 found and fixed some small performance improvements, which do not change any functionality. Especially the position and rotation calls and LINQ call removals are very helpful for performance
Addcalls onList<T>variables intoAddRangeAddRangewill ensure the list is only extended once.String.Lengthis faster than usingEquals(C# docs reference)SetPositionAndRotationhas a small performance improvement (docs).Count()uses LINQ and has a cost..Countdoes the same thing without the LINQ cost.StringBuilder.AppendJoinrather thanStringBuilder.Append(String.Joincontinues: #3680
