>>28290761) MMD is rather unhandy. MikuMikuMoving is vastly more convenient, but not all MikuMiku effects are adapted to its rendering engine. There's also a third program, but I forgot what it was called. Of course, Blender also exists, but its rendering engine takes ages to render, and it's harder to learn than all of them due to being way more versatile.
2) You don't need a particularly good computer to create and run simple scenes, but you need extremely high-end software to smoothly run complex scenes with complex models and advanced effects, as the optimization of both programs is shitty. For example, I cannot run the 9-person Ifuudoudou motion at all if I use complex models, even without effects. However, it works with simple models, although the FPS drops fairly low, using Ryzen 7 2700X, RTX 2060 1755 MHz, and 16 GB DDR4.
3) Not that hard, most of them are publicly available or shared by pirates like the audience of this thread, the bigger challenge is solving passwords used for a lot of them.
