Polygon Budget & LOD Guide

Triangle counts are approximate. LOD0 = nearest camera distance. LOD3 = far background / culled. 3D print counts refer to the STL mesh sent to the slicer.

Use Case	LOD0 (tris)	LOD1	LOD2	LOD3	Notes
Racing game hero car	40,000–80,000	15,000–25,000	4,000–8,000	500–1,500	Interior cockpit adds 10–20k; driver character separate
Open-world traffic car	8,000–15,000	3,000–5,000	500–1,500	200–400	Exterior only; single flat diffuse OK at LOD2+
Mobile game vehicle	3,000–8,000	800–2,000	200–500	—	Baked AO + diffuse; no normal map at mobile LOD1+
RTS unit (camera far)	1,000–3,000	400–800	—	—	Silhouette is key; diffuse with AO baked; no interior
Cinematic / VFX	100,000–500,000+	—	—	—	Subdivision-ready; full interior; PBR textures 4K+
3D print — FDM	50,000–300,000	—	—	—	Watertight required; thick walls ≥ 1.2 mm; no overhangs >45°
3D print — resin	200,000–1,000,000	—	—	—	Hollow body + drain holes; supports for thin parts; watertight

What to Check Before Buying a Vehicle 3D Model

Topology & Edge Flow

Clean quad-dominant topology deforms correctly when animated (suspension travel, door opening) and subdivides without pinching. Open the Proofly 3D viewer, enable Wireframe mode, and look for uniform edge loops around wheel arches and body contours. Triangulated exports are fine for game engines but will not subdivide smoothly in Blender or Houdini.

Hierarchy & Naming

A drivable car needs a clear hierarchy: Body → Wheel_FL, Wheel_FR, Wheel_RL, Wheel_RR. Doors, hoods, and trunks should be separate child objects with correct pivot points at the hinge axis. Unity's Wheel Collider and Unreal's Chaos Vehicle physics both expect wheels on named child bones — misnamed or merged wheels mean your physics code won't find them.

UV Maps & Textures

Game-ready vehicles need a UV0 channel for diffuse/PBR textures and a UV1 channel for lightmap baking (Unity) or Lumen/Raytracing in Unreal. Confirm texture resolution matches your pipeline (2K per part for mobile, 4K for PC/console hero cars). PBR textures should include: Albedo, Normal, Metallic/Roughness (or Specular/Gloss), and AO. Listings that provide all channels in a ZIP save hours of manual texture work.

Scale & Real-World Dimensions

Vehicles at wrong scale break physics and player camera rigs. A standard sedan should be roughly 4.5 m long, 1.8 m wide, 1.4 m tall. An FBX imported at default Unity scale (1 unit = 1 m) should match. STL files have no unit metadata — import into your slicer and verify against real dimensions before printing. Good listings state the dimensions in the description or in the Proofly 3D viewer's measurement panel (toggle with M key).

Collision Meshes

High-polygon vehicle bodies are too expensive for real-time physics. You need simplified collision meshes: a convex hull for the body (Unity: mesh with prefix UCX_), box colliders for wheels, and a simpler compound collider for interiors. Some packs include ready-made collision meshes; others leave it to you. Check the listing "Files" tab to see if a collision mesh layer is included.

Interior Detail

For a first-person or cockpit camera, you need a full interior: dashboard, steering wheel, seats, pedals, and mirrors. For third-person games where the interior is only occasionally visible, a simplified interior with flat window glass (alpha-tested) is sufficient and saves triangles. Check whether the listing includes both exterior-only and full-interior versions — the best packs include both optimised for their respective camera distances.

HiddenMark — Every Vehicle Download Is Watermarked

Vehicle 3D models are expensive to produce and frequently pirated. Proofly embeds an invisible steganographic fingerprint into every paid download — the watermark encodes your purchase ID without visibly altering the mesh. If a creator finds their car model re-sold on another site, they can upload the pirated file to proofly.store/hiddenmark/verify and instantly identify which purchase it came from. For legitimate buyers, the watermark is completely invisible — it does not affect rendering, game engine import, or 3D printing.

Frequently Asked Questions

What polygon count should a game-ready car have?

It depends on the platform and camera distance. For a third-person or racing game on PC/console, a hero car that fills the screen should have 20,000–80,000 triangles on LOD0 with a 3–5 LOD chain stepping down to 500–2,000 triangles at LOD3. For mobile games, keep LOD0 under 15,000 triangles. Background traffic cars (never seen up close) can be 500–2,000 triangles with a single flat diffuse texture. A well-optimised vehicle pack includes at least three LOD meshes, a collision mesh (convex hull or box primitives), and an LOD0 that runs under 30,000 triangles on the GPU-intensive platforms.

What format is best for importing vehicles into Unity or Unreal?

FBX is the most reliable choice for both engines. It preserves hierarchy (body, doors, wheels as separate objects), material slot names, and skeletal rigs if the vehicle has animated parts. Unity imports FBX natively; Unreal Engine uses its own FBX importer. GLB/GLTF works well for Unity 2022+ (via GLTFast) and Unreal 5.0+, and is the standard for web engines (Three.js, Babylon.js). OBJ is fine for static props without moving parts — it carries geometry and materials but no hierarchy or animation. STL is for 3D printing only — no materials, no hierarchy.

Should I look for a rigged or unrigged vehicle model?

For a drivable car in a game, you need a rigged vehicle or at minimum a correctly separated hierarchy: a parent body mesh with child bones or objects for each wheel, suspension arm, and steering wheel. This lets your vehicle physics script rotate wheels independently and steer. An unrigged car (single static mesh) is only useful for decorative parked vehicles, dioramas, or visualizations. For aircraft, a rigged model should have separate control surfaces (ailerons, rudder, elevators, landing gear). Check the listing description for 'rigged' or 'animated' tags, or look in the Proofly viewer — a rigged model will have a skeleton visible in the 3D preview.

How do I 3D print a vehicle model?

Most vehicle 3D models sold for game engines are hollow and non-watertight — they'll print with holes. Look for models tagged '3D print ready' or 'watertight', or check the Proofly listing badge: the viewer shows a 'Watertight' checkmark for manifold meshes. Scale is critical: STL files have no unit metadata, so import and scale in your slicer before printing. A 1:24 scale car is roughly 170–190 mm long. For resin printing (MSLA/SLA), you can print very fine detail but need to hollow the body and add drain holes. For FDM, keep overhangs under 45° or add supports. Separate prints per part (body, wheels, interior) then assemble.

Can I use vehicle 3D models from Proofly in a commercial game?

Yes — most listings include a Commercial license that covers use in games, apps, and simulations distributed for sale. Review the license panel on each model page: Personal covers hobby projects, Commercial covers one commercial product, and Extended covers asset store re-distribution or templates. The license is per-listing, so check before buying. If you need a fleet of vehicles under a single NDA-protected deal, contact the creator via the 'Message Creator' button for a custom arrangement.

What is HiddenMark and why does it appear on vehicle downloads?

HiddenMark is Proofly's steganographic watermarking system. When you download a vehicle model, the file contains an invisible fingerprint that encodes your purchase ID, your account ID, and a timestamp. If the file is ever leaked or resold without permission, the original creator can upload the pirated copy to /hiddenmark/verify and identify exactly which account the leak came from. For buyers this is transparent — it doesn't affect how the model looks, renders, or prints. For creators, it's a traceable DMCA chain of custody for every paid download.
