If you include clothes inside package (and you are not original creator)
than you have to adress that.
-credit original creator inside package & on overview page of your resource (simple copy-paste of depend.txt is not a proper credit).
-50% of license issues can be resolved by leaving proper attribution/credit (link to original creator on hub, if not on hub than patreon,deviantart,whatever)
-NC & ND content is different, leaving just credit is not enough/solution
-you can be 100% safe only if/and/or:
a) content inside your package is your own creation or content is originally released as public domain - (CC0/FC)
b) you properly credited each creator for redistributed and/or referenced (dependencies) content - (any BY)
c) (paid) you don't release
NC content inside own package and/or as referenced (dependencies) content - (NC/NC-SA/NC-ND/PC/PC EA)
d) (free or paid) you don't release (redistribute)
ND content inside your own package or content (.zip) - (ND/ND-SA/PC/PC EA)
Even if content is just referenced as dependency, you're still using that content, so you have to give credit (unless FC).
If you are unsure of the content's origin, simply don't use it/redistribute it....or do
...but than you are running the risk of loosing that content and potential ban.
It's true that there's old pre-var content out there,
and they don't have .var license, for those CC BY 'kinda' applies by 'default'
But that still isn't enough, especially if it's paid pre-var content
or some daz ported content (that's clearly licensed).
make sure to check all policies ?
