Trying to ignore the annoyingly-named \"TextMesh Pro\" directory, underneath an \"Assets\" folder (full path from the root where .gitignore resides is \"Sky Labyr
It seems that you have missed one of the spaces between Text and Mesh. Try adding
Assets/Text\ Mesh\ Pro/
to your .gitignore
Correct answer is:
TextMesh*Pro/
**/TestMesh Pro/
Should also work
