If it works, you did it right

select(3, string.find(name, pattern))
-- or if you use colon syntax
select(3, (name):find(pattern))

This works because string.find(...) returns starting and ending position of the pattern in the string and then captures that you have enclosed in brackets. If pattern is not found, return value is nil.

texture = art/maps/glenumbra/daggerfall_base_0.dds
pattern = "([%w%-]+)/([%w%-]+_[%w%-]+)"
 
string.find(texture, pattern)
--or colon syntax:
(texture):find(pattern)
--returns: 5, 34, "glenumbra", "daggerfall_base"

Pattern "(maps/)([%w%-]+)/([%w%-]+_[%w%-]+)" has one more closure, so thats why I have used select(4,...).
