Custom Asset Models

Custom asset models are user-uploaded 3D models used to represent real-world infrastructure during inspection planning.

They provide geometric context for shot design, helping teams reason about scale, distance, and camera framing when creating shot sheets. Asset models are planning references, not as-built records or engineering-grade representations.

What Asset Models Are Used For

Asset models support inspection planning by:

  • Providing spatial context for camera positioning
  • Improving confidence in framing and coverage
  • Helping validate distances and perspectives
  • Making shot sheets easier to design and review

They are especially useful when planning inspections for complex structures or when standardizing procedures across many similar assets.

Supported File Formats

Shuttermap uses glTF as its native 3D model format.

The following formats are accepted for upload:

  • GLB (preferred)
  • OBJ
  • FBX

Models uploaded as OBJ or FBX are automatically converted to glTF during the upload process. Using glTF directly is recommended when possible, as it provides better performance and more predictable results.

Model Optimization and Preview

Before an asset model is uploaded, it goes through an optimization and preview step.

This process allows you to:

  • Review the model visually before committing it
  • Reduce file size and complexity
  • Minimize data footprint during planning and review

Optimization focuses on improving performance and usability while preserving the overall shape and scale needed for inspection planning.

Using Asset Models in Shot Sheets

When editing a shot sheet, you can select an asset model to display in the 3D scene.

The selected asset model:

  • Appears as the planning reference in the scene
  • Is used to reason about camera placement and framing
  • Does not change the underlying shot definitions

Shot sheets remain valid even if asset models are updated or replaced later.

Best Practices

For best results:

  • Use one asset model per asset type when possible
  • Prioritize correct scale and proportions over fine detail
  • Avoid unnecessary geometry that does not affect inspection framing
  • Reuse models consistently across shot sheets
  • Refine models over time as inspection needs evolve

Asset models work best when they support clarity, not precision for its own sake.

Next Steps

After uploading custom asset models, you can:

  • Apply them when creating or refining shot sheets
  • Reuse shot sheets across projects and assets
  • Use assignments to apply shot sheets to real inspection work
