I forgot exactly what got me into 3d, but I remember when.
I think I was like 12 or 13 (in like 2007 or something) when I got started, I used some shitty program called 3d Canvas. Ironically enough it's still being updated.
I didn't really have any goals or anything with it, I just used to have fun making space ships and making little animations for fun.
Obviously the shit wasn't good by any means, but it was just fun for me.
I made animations about a bunch of things
Batman in his Bat-mobile,
an Alien Abduction thing about a cow that revolts and starts a revolution on an alien planet.
An adaptation of Doom 3, but with Lego graphics.
I didn't really show anyone though. I wish I had backups desu.
A little later I got into Blender, and made a bunch of still scenes. Then a few years later took a 3d animation course in high school, we learned Max. I still have some stuff somewhere from it.
Still used blender at home, then quit.
I'm back into it now, I make wallpapers and shit. People tend to like them, I make some cash for steam games every now and then from it.
I'm not really interested in pursuing any kind of career from it, it's just a nice hobby. I'm almost done with school for graphic design now, and I can see a career out of that though.
