and let’s not forget animation comes (generally) after modeling, texturing, lighting. You’ll find more modeling-pieces being showcased simply because it is the first step of 3d. Naturally you find less showing animations because, well hey, you get the picture
Plus animation is a tricky thing. Extremly difficult for many to even start on animation. There’s a passage in “The Illusion of Life” that mentions how Disney wanted to expand at some point back after their first few movies. Said they wanted a staff of… what was it… 500 animators or something to that effect. But they had to give up, there simply weren’t that amount of quality animators to be found
But hey, I want more animations showed on these forums just as much as the next guy.
