Question 1

What polygon count should a FPP weapon have in a AAA tactical game?

Accepted Answer

For FPP weapons in AAA tactical titles, the standard low-poly delivery range is 8,000–20,000 triangles depending on platform performance budget and modular attachment count. A hero rifle — the primary carry weapon — typically sits at 12,000–18,000 tris. Sidearms run 6,000–10,000 tris. This is the low-poly (baked) mesh; the high-poly reference used for baking runs 60,000–100,000 tris before reduction.

Question 2

How many texture sets does a weapon typically require?

Accepted Answer

A standard FPP weapon uses one 2K–4K PBR texture set (base color, ORM packed, normal map). Modular weapons with distinct attachment material groups may require a second texture set for scope or suppressor families to avoid material ID conflicts. For cosmetic skin systems (as in Squad's attachment skin architecture), additional texture sets per skin variant are standard. Each set should use consistent UV island placement to allow skin layering without UV modification.

Question 3

What's the most common technical failure when importing a weapon into Unreal Engine 5?

Accepted Answer

The most frequent day-one import failure is texture channel packing mismatch. Unreal Engine 5 uses ORM packing (Occlusion in R, Roughness in G, Metallic in B) as its standard. Studios that bake and export for Unity's standard render pipeline or for a standalone Marmoset preview will have channel assignments that produce inverted metallic or roughness response in UE5. The fix is a re-export, not a rebake — but it's a preventable one-day delay that should be caught in the delivery brief, not post-import.

Question 4

How should modular weapon attachments be handled in the UV layout?

Accepted Answer

Each attachment family (scope rail, foregrip, suppressor, barrel extension) should share consistent UV island placement within the attachment texture set. This means the scope from rifle A and the scope from rifle B use the same UV region within their respective material groups — ensuring attachment skins and skin layering systems work without UV modification. Scopes and triggers should not use mirrored UV islands due to FPP-camera symmetry artifact visibility. Document the UV layout rules in an asset spec sheet before production begins.

Question 5

What's the difference between outsourcing weapon art vs. hiring an in-house weapon artist?

Accepted Answer

The decision maps to volume and specialization. For a sustained pipeline of 20+ weapons per year, an in-house weapon artist provides pipeline integration, institutional knowledge, and direct feedback loop with animation. At day rate (roughly $400–$600/day for a senior hard-surface specialist) and employer overhead, an in-house hire costs $120,000–$180,000+ per year in total employment cost. An outsourced studio on a per-batch or retainer MSA covers comparable capacity at $20,000–$50,000 per weapon batch depending on scope and complexity — without the onboarding cycle, benefits overhead, or the production gaps between projects. The break-even typically sits at around 8–12 weapons per year: below that, outsourcing is more capital-efficient; above that, the math shifts based on pipeline integration value.

Question 6

What should a weapon art brief always include?

Accepted Answer

At minimum: camera context (FPP/TPP/hybrid), platform performance budget (tri count ceiling), texture resolution and channel packing format for the target engine, modular attachment list with UV island rules, material zone map with PBR calibration targets per zone, animation constraint list (which elements will animate and how), and LOD level count with acceptable triangle reduction per level. This isn't a wish list — it's the difference between a first-pass approval rate above 75% and one below 50%.
