When the Job Itself Isn't Defined

I've spent the past few months preparing for my adult trainer/tutor certification while building AniMotion

An opportunity to dive deep into the gameplay animator profession, away from chaotic productions. To step back. To structure what I've learned over 15+ years.

And to discover something unsettling: There is no defined framework for the gameplay animation profession.

No official structure. No clear criteria. No defined scope.

Engine integration? Keyframe animation? Mocap cleanup? Retargeting? Scripting? Rigging? Automation?

All these tasks can be required of a gameplay animator depending on the studio, project, or team.

tache animateur gameplay — It's obviously impossible to cover all these aspects with a single person.

When I started in 2008, the term "gameplay animator" didn't even exist in job postings.

We were looking for an animator, period. Cinema or video games, same job title. Except video games had a bad reputation among CG animators.

Today, the difference is striking.

Gameplay animator positions of all kinds are pouring in. Perception has evolved. Games are more complex, skills more specific, and there's now a real distinction between animator profiles.

Yet, the boundaries remain very blurry.

With this unstable foundation, how do you hire the right profiles?

How can a junior know what's expected of them?

While preparing my certification presentation, I developed what could be the ideal way to train a junior if everything was properly prepared. If the studio was supportive. If we took the time to mentor. If the skills to master were identified and structured.

An ideal that rarely exists in real production. But should exist.

What This Mentorship Really Changes

Training a junior in engine integration isn't about teaching them to click the right buttons.

It's teaching them to think like a professional. To analyze. To self-correct. To contribute.

A well-mentored junior:

Iterates faster (tests themselves)
Understands technical constraints (integrates, sees limitations)
Communicates better (argues their choices)
Becomes quickly autonomous (self-evaluates)
Shares with others (documents, trains)

But most importantly: they no longer endure the profession. They build it.

They don't just execute: they understand, question, improve.

And that's exactly what's missing today in gameplay animation.

A profession that's still unclear. Juniors who struggle. Studios that don't know how to train them. Overwhelmed leads who reproduce what they experienced without knowing how to do otherwise.

With AniMotion, I want to change that. Create structured training. Provide concrete tools to studios. Give juniors the benchmarks they need to progress confidently.

Not "figure it out yourself." But "here's how to think, analyze, progress."

Because in a profession as exciting as ours, understanding the right reflexes shouldn't take years, especially when we can transmit them in a few weeks.

Why Engine Integration Becomes Essential

15 years ago at Quantic Dream, roles were clear:

Juniors/mids animated in Maya or MotionBuilder
Anim techs created tools to facilitate animators' work
Integration was reserved for leads and senior animators—only they manipulated state machines and validated results in the engine

Today, everything has changed.

Games are more complex: procedural IK systems, motion matching, 2D blend spaces, layered animations, animation cancelling, blend per bone. Teams can't keep up. There aren't always enough senior anim techs to handle all ABPs, state machines, and montages.

And especially: Unreal Engine has become mainstream.

A junior who knows Unreal can become operational faster. But they're expected to master: FBX import/export, root motion, state machines, notifies, montages, compression, debug via Animation Insights.

On recent projects I supervised, juniors integrate their own animations from day one.

Out of necessity. Because iteration is faster if the animator tests themselves. Because an autonomous junior on integration immediately becomes more valuable.

But here's the problem: no school teaches engine integration. And most studios have no documentation.

Juniors learn by trial and error. Searching for info and asking around. Without really understanding the "why" behind each step.

I've been there. Searching alone, doubting, correcting without understanding... until the pieces finally came together.

This chaotic journey made me want to build a method that doesn't just transmit gestures, but a way of thinking, analyzing, progressing.

My 4-Phase Method: Building Autonomy Step by Step

Phase 1: Observe and Understand

Principle: Show while verbalizing my approach

The junior observes me integrate several animations. But I don't just perform the actions: I verbalize my thinking.

"Here, I first check the file's framerate. Why? Because if I export at 60 when our target is 30, the engine will have to convert and that creates micro-offsets."

"I experiment first in the test scene. That way, if it crashes, it doesn't block the whole team."

"I see sliding. I don't panic. Usually it comes from a root motion error. I'll check the animations."

This verbalization is crucial. It shows how a senior reasons, anticipates, debugs. Not just how they click.

At the end of each demonstration, I make them talk:

"What did I test before integrating the animation?" "Why did I check that parameter?"

This questioning forces them to think about the process, not just memorize gestures.

Objectives: Understand the pipeline logic, observe how a professional thinks and solves problems, start building their own reasoning.

Phase 2: Practice Together

Principle: Guide through questioning

The junior now integrates their own animations. I give them a checklist to verify steps but especially I guide through questions.

"Before exporting, what do you need to check?" "What framerate did you choose? Why?" "How will you test that it works?"

If they don't know, I don't give the answer directly. I rephrase:

"We saw yesterday that framerate could be a problem. Do you remember why?"

This questioning forces them to mobilize what they observed. To think, not just apply.

When they make a mistake, I don't correct immediately.

I ask: "You just exported. What would you do now to verify it's good?"

If they identify the error: perfect, they learn to self-correct. Otherwise, I guide: "Look at your naming convention. What does it look like? And the other files in the folder?"

I lead them to the solution, without giving it.

And I systematically acknowledge good reflexes:

"You thought about root motion before I even asked." "You detected the bug by reading the logs. You're progressing."

This isn't flattery. It's factual. Naming what's well done anchors good practices.

Objectives: Develop their reasoning, lead them to self-correct, understand the "why," not just the "how."

Phase 3: Build Autonomy

Principle: Work alone, analyze together

The junior integrates alone. Tests. Submits the result to me.

But before giving my feedback, I ask them to self-evaluate:

"So, what do you think of this integration?" "Did you follow all the steps?" "Is there something bothering you?"

Often, they identify problems themselves. Sometimes, they see things I hadn't noticed.

This self-evaluation develops their critical sense. They no longer depend on my validation to know if it's good.

When there's a problem they didn't see, I analyze with them instead of just pointing out the error:

"Look at your animation in-game. See that slight sliding? Where could that come from?"

We analyze together. I don't give the answer right away. We think.

"Root motion? Transition too fast? Export problem?"

We test hypotheses. They learn to debug methodically.

Important new element: documentation becomes a reflection tool.

"Now that you've solved this root motion bug, document it. Not just for you. For the next person who'll have the same problem. How would you explain what you did?"

This documentation forces them to formalize their approach, make it transmissible. It's a powerful reflexivity exercise.

I also pair them with an experienced animator.

Not for the other to do it for them. But to multiply perspectives, approaches, ways to solve problems.

During collective reviews, I encourage their expression:

"Explain your choice on blend parameters."

It forces them to argue. Defend their technical choices. Develop their analytical capacity.

Objectives: Autonomy on simple integrations, self-evaluation capacity, beginning of transmission.

Phase 4: Become a Force for Improvement

Principle: Move from executor to contributor

The junior no longer just follows the process. They question it. They improve it.

"That step there, do you find it logical? Or do you think we could do otherwise?" "You struggled with this. How could we simplify it for the next ones?"

I encourage them to analyze the pipeline itself. Identify friction points. Propose.

Concrete example:

"I see you spend 10 minutes each time configuring the same blend parameters. Any ideas to save time?"

"Could we make presets?"

"Exactly. Go see the programmers, explain the problem, propose your solution."

They no longer just receive instructions. They contribute to pipeline improvement.

This phase develops:

Their global workflow vision
Their capacity to identify systemic problems
Their communication with other departments (programmers, game designers)
Their professional posture, not just learner

I also ask them to train the next arriving junior.

"Remember your struggles at the beginning? Explain to them how you wish it had been explained to you."

Training someone is the best test of mastery. If you can transmit, you truly understand.

Objectives: Complete autonomy, pipeline analysis capacity, contribution to collective improvement, peer transmission.

The 3 Delicate Situations (and How to Handle Them)

1. The Junior Who's Stuck and Doesn't Dare Ask

Signs: Spending time on a problem without progress. Seems hesitant. Waits for me to come to them.

My approach:

I never let them stay stuck more than an hour. But I don't arrive in "I'll solve your problem" mode.

I lead them to verbalize:

"What have you tried?" "What do you think is the problem?" "If it were me, where would you search?"

Often, simply verbalizing unblocks them. They find the solution themselves by explaining.

If they're really stuck, we analyze together:

"OK, let's look at the logs. What do they say? Does that give you a lead?"

And if we don't find it, I teach them to reach out to the right people:

"This is clearly an engine problem. Let's see the gameplay programmer. But first, prepare what you'll say: what's happening, what you've tried, what you think."

Objective: Learn to ask for help professionally, at the right time, with the right information.

2. The Junior Who Goes Too Fast and Skips Verifications

Signs: Validates without testing completely. "Seems to work."

My approach:

I don't let it pass. But I don't just make them redo it either.

"You validated. Explain how you tested."

If they haven't tested completely: "What if you tested with all characters? What could happen?"

I make them think about consequences:

"Imagine: you validate now. In 3 weeks, the game designer tests the complete level. They find a bug in your animation. What happens?"

"I'll have to redo everything..."

"Exactly. And you'll have forgotten what you did. It'll take 10 times longer. Whereas now, if you test thoroughly, it takes 10 minutes."

I don't make them feel guilty. I show the logic.

And I ask: "So, what are you going to do?"

They make the decision themselves. They choose to retest. I don't impose.

Objective: Integrate rigor through understanding, not obedience.

3. The Junior Who Lacks Confidence

Signs: "Is it good? Can you check? I'm not sure..."

My approach:

I reverse the question:

"You, what do you think?"

"I don't know..."

"Did you follow your checklist? Everything validated?"

"Yes."

"Did you test in real conditions?"

"Yes, it works."

"Then why do you doubt?"

Often, there's no objective reason. It's just lack of confidence.

I make them verbalize their validation criteria:

"How do you know it's good? What are your indicators?"

When they list them, I respond: "So according to your own criteria, it's validated. You can trust yourself."

And I de-dramatize error:

"If there's a problem, we'll fix it. But look at your last 10 integrations: how many had a bug?"

"None."

"So statistically, you're reliable. Trust yourself."

Objective: Develop their own technical judgment. Become autonomous in validation.

Measuring Progress: Beyond the Result

Evaluating a junior on engine integration isn't just looking at whether the animation works. It's observing their approach, reasoning, autonomy.

During regular check-ins, I observe them integrate a complex animation and note:

Do they check parameters before exporting?
Do they test as they go or all at the end?
How do they react to a bug?
Do they document their choices?

Then we analyze together. I always start with successes: "You tested as you went, detected the problem early. That's exactly the right reflex."

Then areas for improvement: "On the root motion debug, you took time. What blocked you?"

I make them think about their own solutions rather than giving the answer.

What really matters:

Technical conformity: Pipeline respect, absence of bugs
Approach: How they tackle problems, how they debug
Autonomy: Do they self-correct? Do they reach out at the right time?
Reflexivity: Do they document? Can they explain their approach?

The ultimate indicator: Their animations work in production. And especially: they know why they work.

Why Studios Don't Do This Today

Training a junior takes time. Attention. Preparation.

And in production, we never have time.

Deadlines are tight, leads overwhelmed, seniors already in overtime. Add structured mentorship? "We don't have the bandwidth."

Result: the junior figures it out. Learns on the job. Makes mistakes. The team corrects. The junior doubts. And sometimes, drops out.

Yet, today's leads are often better prepared than before.

Many have followed management training, know how to supervise, create connections, establish frameworks.

But accompanying a junior in real skill development is something else.

It's a tutor role, still poorly formalized, rarely equipped.

And without clear benchmarks, even the most caring leads end up reproducing what they experienced: "struggling at the beginning is normal"

Except "struggling" isn't a pedagogical method.

And even in constrained contexts, we can lay foundations: verbalize reflexes, guide through questioning, document errors.

It's not the duration that counts. It's the quality of mentorship.

And that saves precious time later.

AniMotion's Vision

That's why with AniMotion, I want to create concrete tools to structure this mentorship.

Not theory.

Interview guides. Evaluation grids. Ready-to-use pedagogical progressions.

And training that respects the real way of learning.

So studios can train their juniors effectively.

So juniors have a clear framework.

So this profession finally becomes structured.

Because in a profession still unclear like gameplay animation, juniors need clear benchmarks, a supportive framework, and real structured skill development.

Not throwing them in the deep end and letting them figure it out.
