——the apex 3d standard · v1

What “import-ready” actually means.

The 3D marketplace is full of files labelled “clean” and “ready-to-use” that fail the moment you import them. Bad scale. Broken UVs. Hidden geometry. No textures. We don’t think that’s acceptable, so we publish the spec every Apex model passes before it ships. Audit it. Compare it. Hold us to it.

——10 requirements · every model · no exceptions

The spec.

Topology

Quad-dominant. No n-gons on deforming meshes. No non-manifold edges. No hidden interior junk geometry. Clean enough to subdivide, weight-paint, or modify without surprises.

Real-world scale

Modelled in meters. Origin at a logical pivot. +Z up, -Y forward (Blender/glTF convention). A 3-seat sofa is 2.2m long. A coffee cup is 9cm tall. Plug it into a scene and it sits right.

UVs

Non-overlapping. Consistent texel density across surfaces. No wasted UV space. Painters and texture artists can extend the maps without re-unwrapping.

PBR textures

Full PBR set on every model: Albedo, Normal, Roughness, Metallic, Ambient Occlusion. 2K for props, 4K for hero models. Power-of-two dimensions. Named consistently across the pack.

Naming & hierarchy

Clean object names. Logical parenting. No Object_001.001.002 garbage. Drop the model in your scene and the outliner makes sense at a glance.

Polycount + LODs

Within the stated budget for each pack tier. Game-ready packs ship with LOD0 / LOD1 / LOD2 for performance. Hero models ship at higher density with optional decimated variants.

Import test

Opens clean with zero errors in Blender. Imports cleanly into Unity OR Unreal. Renders correctly in the web viewer (Google model-viewer). We run the test before it ships — you don't have to.

AR test

USDZ files are tested on iOS Quick Look. The model places correctly in real-world space at the right scale. Required for our Retail & E-Commerce pack, included on every other model where relevant.

Original IP only

No branded logos, trademarked designs, or recognizable real-world products / characters. Generic and original only — protects your project AND ours from takedowns and legal exposure downstream.

Commercial license included

Every download includes the Apex commercial license file. Use the model in your products, your client work, your games, your ads. Resale of the raw file as a 3D asset is the only thing we restrict.

——what’s in every download

Every format you actually need.

Format	What it is	When to use it
GLB	Web + AR (Draco mesh + KTX2 texture compression)	three.js, model-viewer, Shopify AR, mobile AR. The primary format.
FBX	Game engines with rigging data	Unity, Unreal Engine. Animation-ready.
OBJ + MTL	Universal, no rigging	Any 3D tool, fallback when FBX or GLB isn't supported.
USDZ	iOS AR Quick Look	iPhone / iPad AR previews. Apple's native AR format.
Textures folder	Full PBR map set, 2K / 4K, power-of-two	Re-baking, editing, or porting to a custom shader.

——why we publish this

A spec only matters if you can check our work.

Every model on the store carries an “Apex Verified” badge that links straight back to this page. The spec is the contract. If a model you bought doesn’t meet it, email info@apexflowlabs.com and we’ll fix it or refund it.
