The Art Team over at World of Warcraft have been hard at work updating models for Warlords of Draenor. The latest ArtCraft takes a look at the animations of the male Tauren models. The team and players alike were already excited over the re-modeling of the Bulls due to all the details that were added to them by the Character Art Team.
Each team member explained what went into giving life and motion for the Tauren animations. We’ve compiled just a few quotes and images from the original article. Be sure to check out the full article over on Battle.Net.
Tweaking the male Tauren was a lot of fun because we were able to add a lot more weight than the previous model had and make the Tauren feel bigger and beefier.
Since the facial animation system worked so well with the Pandaren in Mists of Pandaria, with the updated models we wanted to add the same life and emotion they deserved. In the past the character models only had a jaw bone that could be animated, but now we’re able to add movement to the brows, eyes, cheeks and mouth. We’re able to properly make them smile, look angry, and talk.
We also create a “face file” with several preset expressions the animators can use while working. It’s a lot faster than creating a new pose from scratch. If they need a sad or angry face, they can start from the preset ones, and then adjust from there to make it more unique.
We also create several mouth shapes, or phonemes, for use in talking animations. Again, posing the face is time consuming, so having a jump start is extremely helpful. It also makes the character feel like it was animated by one person, when there’s actually a big group of us working on them at one time.
For Warlords of Draenor, we wanted to improve the locomotion of WoW’s player characters with brand new rigs. These new rigs are capable of doing so much more in terms of fidelity of motion for our characters, and we wanted to showcase that as much as possible.
Everyone who plays WoW is familiar with their character’s idle and run animations—those are the two you see the most. We wanted to really take a look at what made the old player model animations successful, and what made them so iconic. Our job was to then retain the spirit of the old animations, but clean them up so they would look epic on the new rigs. […] Some of these runs and walks were animated over 10 years ago!
The first thing we did when we cleaned up an animation was ask ourselves a series of questions. What are some of the areas that could use touching up? Does the center of gravity on the character feel skewed? Is the character leaning appropriately when moving in a direction? How can we shift the timing to give this animation a greater sense of weight?
Once we had identified what needed polishing we went straight into Maya and got to work. A popular method of cleaning up locomotion animations would be saving the contact poses, major breakdowns, deleting the in-betweens, and smoothing out the motion from there.
For the majority of the character cleanup phase, the team focuses on three main things: cloth, hair and the face. Cloth includes a front and back tabard and a cape. Hair can be anything from a back ponytail, a front ponytail, pig tails, beards of varying sizes and shapes, or a combination of all of these. We also add facial animation, which adds a lot of character and life to the model. Occasionally, we will also fix minor posing issues or any errors, like jittering.
All of our character animations are hand keyed, and not dynamically simulated within the game engine or created through motion capture. This allows us to have complete control in shaping the movement and style for each character, and it adds a unique life to the characters you can’t really get any other way.
It is astounding how adding a simple facial expression can instantly bring a character to life. It’s always incredibly rewarding to take an old animation and see what even small changes can do to vastly improve it.
Due to the sheer volume of animations that exist for player characters, our goal of having updated models in time for Warlords of Draenor, and the need to animate all the new creatures and objects going into the expansion, we have to prioritize our time. We’ve broken the cleanup passes on character revamp animations up into phases. Phase 1 has all of the locomotion animations (walk, run, etc.) as well as all the emotes and spell casts. Phase 2 deals with the combat animations (attacks, stuns, etc.), and phase 3 is a catch-all for the remaining animations (swimming, fishing, etc.). Regardless of the phase, every animation is touched in some form or fashion, but phase 1 gets the most love since those are the animations are seen the most.
