$uid(N) emits a v4-random id as 32 hex digits without hyphens, which is what Unity .meta guids need, but some export formats require the canonical hyphenated UUID form (e.g. the manifest of Imaginando VS 2 shaders, see RodZill4#1533). $uuid(N) returns the same cached id as $uid(N) for the same index, in 8-4-4-4-12 hyphenated form (the version/variant bits set by get_uid() already make it a valid UUIDv4). Existing $uid() users are unaffected, and the two patterns cannot be confused by the regexes since "$uid(" is not a substring of "$uuid(".

$uuid()template function for hyphenated UUIDsFollow-up to #1533, where the unhyphenated output of
$uid()is listed as aknown limitation.
$uid(N)emits a v4-random id as 32 hex digits without hyphens — exactly whatUnity
.metaguids need — but some export formats require the canonicalhyphenated UUID form; the manifest of Imaginando VS 2 shaders is one example.
The hyphenated form cannot currently be produced inside a template.
This adds
$uuid(N):$uid(N)for the same index, formatted as8-4-4-4-12 —
get_uid()already sets the version/variant bits, so the resultis a valid UUIDv4 (e.g.
babfc75f-178c-44e3-9ef5-89208122f156);process_uids()alongside$uid(); existing$uid()users areunaffected, and the two patterns cannot shadow each other since
"$uid("isnot a substring of
"$uuid(".If this lands together with #1533, the Imaginando VS 2 target's manifest line
can switch from
"uuid": "$uid(0)"to"uuid": "$uuid(0)", removing thatcaveat entirely — happy to update #1533 accordingly.
