Let me tell you a story.
I’ve met a type of mindset much like yours plenty of times on the Steam Workshop forums, where people believe there is this silent rule that modelers will always provide the audience their content without ever so much as making a peep. It even happens commonly there for people to post topics requesting usable models of anything hip and happening, ripped or made from scratch if ripping is not possible, emphasizing “please I need it!”, and initially, never even stopping to think what the modeler might want in return for his service. Either that, or they offer a measly in-game item he has no use for. You won’t believe the amount of times someone has come to comment on my profile page or workshop to say “make this thing please”. There was even someone who asked me to make the entire cast of the show My Life as a Teenage Robot! No joke!
To rub additional salt into the wound, anything I published there was later indiscriminately ripped out of the engine it was solely intended for and then refashioned and distributed for Blender, C4D, or even made profit off, without my prior consent or knowledge.
So really, the best I can get out of your post if I wrap my mind around it is that you just want your goods to stay free for…whatever means you used them. For entertainment? Profit? Doesn’t matter. But you would still call us greedy. Hmm…
You would consider me a ‘true modeler’ by your logic, but I’m not. 3D modeling is indeed a hobby to me, but there is a very distinct difference between a hobby and professional job. If it’s not a professional career for me, then I’m not a (true) modeler. I’m an amateur at best, and like you say, a hobbyist. And that’s fine. But try not to mix the two up.
But I would hate to make unnecessary drama. Sketchfab hardly has changed and it has only begun. This place respects the modelers, and I mean it when I say I feel respected here. Modelers, true modelers, who may be low on cash, are now offered a means to get a little something back for what they create. This in turn helps keep them going. And I think that’s an amazing step forward. Remember, everyone here is a human with wants and needs. Don’t turn this into a ‘Steam Workshop’. That’s the last thing we would want.
I hope I’ve been able to provide a new perspective and shed some more light on the subject. There will still be models out there for free for you. That option won’t go away as far as I’m concerned.
