Permissions
> It's open-perms: Open my stuff, borrow it, learn from it -- I did so from others, and so I am in no place to be stingy about it. I uphold and uplift the community by doing so, and as such I expect the same from you. DP and other forms of money though is kind of iffy, but so long as you did something significant and transformative (fair-use rules), I'll be cool with it. Assets from others might need their permissions though.
> Give Credits: Not all of these stuffs are mine alone, OpheliaNeoma's explosion recolors for one. Though it is something I asked of her, I do believe that proper credits are in order. Same applies to all authors that helped me.
> For Repackers: Yes, you can translate it, make a compressed-texture version, and/or upload it on another site. Note that I do update a lot, for fixes. I do not decry people for wanting an AIO package, but I would prefer that my mod be treated with respect and dignity, not just for me but for the sake of the Giants I stood over. There's a reason Dak USED to have open-perms with his mods -- do not take advantage of the community's good-will.
> For Borrowers: As in those who wants to bring the gun outside of Boston, if-you-know-what-i-mean. Don't asset flip.
I understand that this might be presumptuous of me, because I'm sure the quality of my weapon isn't up to par.
I don't judge you for borrowing mod guns, they are after all awesome, and I'm sure
