Free browser tool / LM5

Check a GLB before it reaches your store or shoppers.

Open a self-contained model here, rotate it, and see plain outcomes for the four uses this GLB-only checker can evaluate.

  • No model upload
  • No email required to see the result
  • Local viewer, validator, and optimized-format support
  • Optional editable Excel QA workbook

Private browser check

See what shoppers may experience before you publish.

Choose a self-contained GLB to open it here and check four practical uses. The selected model stays in this browser and is never uploaded.

No model upload. The checker loads its viewer, validator, and compression decoders from this website, while your selected GLB remains in browser memory.

Optional QA handoff

Carry the browser result into an editable acceptance record.

The local check cannot prove appearance against an approved reference, final store integration, rights, or behavior on every customer phone. Use the worksheet below when those human acceptance checks also need owners and evidence.

Acceptance record

Review the asset in its real delivery environment

Mark what you have observed. Unknown is a useful answer when acceptance evidence does not yet exist.

Asset context
Geometry and transforms

The asset uses verified real-world dimensions and scale.

Compare the model against an approved product dimension rather than judging scale by eye.

Origin, pivot, up axis, forward direction, and resting position are correct.

Confirm the asset opens in the intended orientation and rotates around a deliberate pivot.

Normals, smoothing, thin surfaces, and visible seams render correctly.

Inspect silhouettes, mirrored parts, transparent surfaces, and hard edges under neutral lighting.

Materials and textures

Materials remain recognizable under the target viewer's lighting.

Check roughness, metalness, normal direction, opacity, and color against an approved reference.

Texture dimensions, channels, compression, and color space match the delivery budget.

Identify oversized maps, duplicate textures, unsupported formats, and color-space errors.

Material and product variants preserve naming and visual consistency.

Test representative variants and verify that every expected material slot is addressable.

Delivery and performance

Compressed file and texture transfer sizes meet the agreed performance budget.

Use the target experience's documented budget; this checklist does not prescribe one universal size.

Loading, decoding, first render, and interaction remain stable on the target devices.

Observe first load and repeat load separately, including failure and fallback states.

Viewer and integration

The asset has been tested in the actual mobile browsers and viewer used at launch.

A desktop editor preview is not acceptance evidence for a mobile commerce experience.

Camera controls, keyboard access, reduced-motion behavior, and non-3D fallback are defined.

Confirm the product remains understandable when 3D is unavailable or inappropriate.

AR acceptance

Android AR scale, placement, appearance, and interaction are tested on a representative phone.

Mark not applicable when Android AR is not planned; otherwise compare Scene Viewer with the approved product appearance.

Ownership and operations

Source ownership, third-party rights, versions, and the future update owner are recorded.

A technically valid file can still be unusable when rights or maintenance ownership are unclear.

What the checker separates

A file problem, a performance recommendation, and a real-device check are different findings.

The first view explains shopper and store outcomes. Exact measurements, validator messages, extension names, and rule evidence remain behind Technical details.

Test the finished store page and Android AR experience on the devices and connections your customers actually use before publishing.
