I know how hard it is to code stuff, but, in the end, if you keep thinking this way you have to say to yourself, why the fuck do you even code then?
It's not like you code to give yourself an ego, right? I mean, requiring people to give you credit for work to help others is kind of requiring people to stroke your egos. I can understand you don't want people to steal custom work, like sprites you've created yourself or edited from existing ones, or custom textures, or high-res versions of low-res models, but creating model converters is coding. You create these programs for others to use, not requiring them to give you all the credits.
It's like the creator of TileMollester, would he require you to give him credits? No, of course not. It can rip all kinds of things, like textures or sprites, and I'm pretty sure that program took even more work than most model converters.
Hell, take LunarMagic, a Super Mario World hacking program. It took several years to perfect that fucking program. And how many people made game hacks of Super Mario World? It's an aweful lot. Do you really think these people give credits to the creators of LunarMagic? No. And you know why? Because the creator doesn't give a fuck what you do with it.
And we have a lot more programs. TPL / BTI converters, SSBB extractors, whole programs to rip various SCUMM based games, you name it.
So really, I think some programmers should just stop this bullshit. We have other means as well, and those people who do release their programs without any strings at least do get more credit.
And quite frankly, when it comes to model rips, I'd rather not have my name attached to it.
