Interviews: Why I Ask About Retopology, Not Renderers

If you're a game artist, you've likely been asked in an interview, "Which renderer do you prefer—Unreal or Unity?" But that's the wrong question. I've conducted dozens of interviews, and I've learned that the tools an artist name-drops tell me almost nothing. What actually separates a skilled game artist from a hobbyist is their mastery of the foundational pipeline—the unglamorous, behind-the-scenes work of retopology, UV mapping, and LOD management. This article is my myth-busting FAQ on what to ask (and what to listen for) in a game art interview.

Why do you ask about retopology instead of sculpting?

Because sculpting is the fun part, and anyone can learn it. But retopology is where the real craft shows. A dense sculpt from ZBrush is beautiful, but a game engine can't render millions of polygons per character. You need a clean, low-poly mesh with purposeful edge flow—that's the difference between art that looks good in a viewport and art that actually works in a game. I once interviewed an artist who showed a gorgeous high-poly dragon, but when I asked about the retopology, he admitted he'd just used ZRemesher and never checked the edge flow around the wings. That told me he didn't understand deformation. (Game art pipeline, Wikipedia)

Don't modern engines like Nanite make retopology obsolete?

That's a common misconception, especially with Unreal Engine 5's Nanite. Nanite does let you import film-quality meshes with billions of polygons and handles LODs automatically—it's genuinely revolutionary. But it's not the whole industry. Most games still run on Unity, mobile, or older engines where you have to respect polygon budgets. Even in Unreal, Nanite has limitations for skeletal meshes and animation. So if an artist says "Nanite means I don't need to retopologize," I know they haven't shipped a real title. The fundamentals still matter. (Unreal Engine documentation, Epic Games)

What's the single most revealing interview question about UVs?

I always ask: "How do you handle UV seams on a character?". UV unwrapping is the step everyone dreads, but it's critical. If an artist can talk about placing seams in hidden areas, like under the arms or behind the ears, and can explain texel density—how many pixels per world unit—they get my attention. A lot of artists think UVs are just about "getting it unwrapped," but it's really about optimizing texture space and avoiding visible stretching. I remember a candidate who showed me a perfect UV layout for a sci-fi helmet, with shells arranged to maximize the 2048x2048 texture, and he explained why he put the seam along the back edge. That was the moment I knew he was a pro. (UV mapping, Wikipedia)

Is it fair to ask about LODs in an interview?

Absolutely, and it's one of my favorite topics. LODs—level of detail—are the unsung heroes of performance. In a typical game, you might have a character with 15,000 triangles at LOD0, dropping to 800 triangles at LOD3. I ask candidates to describe a LOD chain for a character: at what distances do you switch, and how do you simplify the mesh? A weak answer is "I just decimate it." A strong answer mentions preserving the silhouette, reducing edge loops, and maybe using normal maps to fake the detail. I once had an artist talk about using a LOD system that reduced triangle counts by 50% between levels—that's a solid rule of thumb.

What about baking and normal maps—should I quiz them on that?

Yes, because baking is where the high-poly detail gets transferred to the low-poly mesh. But here's the thing: I don't just ask if they know how to bake. I ask about the pitfalls. Do they know to fix overlapping UVs? Do they understand that a normal map is just a texture that stores per-texel surface directions, faking detail without adding polygons? The best answer I ever got was from an artist who explained how he bakes ambient occlusion into the normal map to fake shadow in crevices. That shows a deep understanding of the PBR pipeline. (Texture baking, Western Kentucky University; Normal mapping, Wikipedia)

How do I spot a technical artist in an interview?

Technical artists are the bridge between art and engineering. They write shaders, build tools, and enforce asset standards. In an interview, I ask about texture compression formats. A good tech artist will mention BC7 for PC, ASTC for mobile, and BC5 for normal maps. They'll also talk about draw calls—how to batch meshes to reduce them. I once interviewed a candidate who explained that dynamic batching only works for small meshes of roughly 225-300 vertices, and he knew when to switch to static batching or GPU instancing. That's the kind of detail that separates a tech artist from a generalist. (Unity Manual: Draw call batching; Technical artist roles, gamesindustry.biz)

Why do you care about stylized art vs. realism in interviews?

Because stylized art tends to age better. Look at The Legend of Zelda: The Wind Waker—it still looks fresh decades later, while many realism-heavy games from the same era look dated. I ask candidates about their favorite art style and why. If they say "I only like photorealistic PBR," I worry they don't understand that strong art direction beats raw fidelity. The best candidates can talk about how stylized art uses color, shape, and lighting to create a cohesive look, and they're not afraid to say that realism isn't always the goal.

So, the next time you're interviewing a game artist, skip the renderer questions. Ask about retopology, UVs, LODs, and baking. Ask them to walk you through a specific asset from start to finish, and listen for the details—edge flow, texel density, draw calls. The most important thing to remember is this: tools change, but the fundamentals of the game art pipeline remain constant. An artist who masters the basics can adapt to any engine, any software, and any art style. That's the artist you want on your team.
