I don’t think some people understand why it takes so long for them to make the next volume and how much work they have to put into it.
On one hand, here’s what everyone usually thinks about when it comes to the production of the episodes:
Recording the music and songs
Animating - the fight scenes mainly go to Monty, a lot of casual scenes are mocapped, people have to animate the facial expressions
What a lot of people don’t think about in regards to those things:
Voice acting: They don’t just go into the recording booth and go boom boom boom done. They do several takes of every part they voice, so the crew can use whichever take sounds best. Remember that they don’t know what it’s going to look like in the finished product, and their recording booth only allows for one person to record at a time, so they’re not going to hear what the other voice actors have done. Instead, they have to play off of Miles and Kerry reading lines to them.
Music and songs: First of all, apparently Jeff and Casey don’t live in Austin. Thus, they send the music to the RWBY crew. Second, the songs we hear in the episodes aren’t always finished. They’re just the episode editions of the songs. When we first heard Red Like Roses Part 2, the full version wasn’t finished yet. Same with Die, Caffeine, and Sacrifice from volume 2.
Animating: Facial animations probably have to wait until the voice acting for that scene is complete, so they can match the lips to the characters’ lines while they animate their expressions. There’s also the fact that we’re talking about an entire team of animators working on different scenes. They have to collaborate and make sure that what they do lines up well.
On top of all that, a lot of people just plain don’t think about the fact that every new volume means new models and textures are needed.
If they introduce a new character, that’s another model and more textures they need to make. Not only do they have to build the model, they have to set up its rig and make sure that the rig will move correctly and smoothly. Now that they use collisions, they have to add collision boxes to the model and make sure that they’re going to react the way they want.
If our characters go to a new place, any place at all, they have to build and texture that place.
Think about it. In volume 2, how many new places have we seen in Vale?
And, of course, there’s Tukson’s Book Trade:
What new areas of Beacon have we seen?
Not to mention that the gears in Ozpin’s office and even inside his desk all constantly move, and they built the exterior of his office for that shot where the camera goes in through the window.
Then, there’s Mountain Glenn:
And the interior of the train:
And the interior of Ironwood’s giant airship:
As for character models, how many characters were introduced in volume 2?
Mercury (He was just a 2D image in the volume 1 after credits scene)
Emerald (She was just a 2D image in the volume 1 after credits scene)
The White Fang Lieutenant
Not to mention they had to make Velvet’s new outfit and Team RWBY’s alternate outfits.
None of this is including the fact that the crew changed the textures on everything for volume 2.
So, now, imagine how much they’re probably going to have to do for volume 3. Let’s all take a moment to appreciate how much work they do.
