This pull request fixes an issue where an asset's
.meta
file would not be deleted when the asset itself was deleted.Although the meta file was actually deleted, it was shortly after being re-created by the
UpdateAssetReferences
listener which calls thegetOriginal()
method on theAsset
, which ended up callingmeta()
and because of a meta file not being found for the asset, it created one.This PR attempts to fix that issue by checking if the asset itself actually exists before writing the meta file to disk. If one doesn't exist, it'll now just return an empty meta array.
Fixes #7042.
