Craft seems to create asset files and folders with permissions 775 and 664. My host has restrictions in place to not serve folders/files with these permissions.
Where can I change this?
Of course as soon as I post this, I find the answer.
'defaultFilePermissions' => 0664,
'defaultFolderPermissions' => 0775,
The default settings are there, I just need to add them to my own config.
