The short version

  • Each has a real cost: Bentley iTwin Capture Modeler the rename from ContextCapture is more than cosmetic: licensing moved into Bentley's subscription and consumption model, and existing perpetual users should confirm what a renewal converts to before assuming continuity of cost.; Sight Machine onboarding is a data engineering project measured in months per plant, so value arrives long after the contract starts and the internal sponsor needs the patience and budget to survive that gap.
  • They diverge on capability: Bentley iTwin Capture Modeler covers Aerial triangulation, Sight Machine covers Unified plant data model.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Bentley iTwin Capture Modeler

  • The rename from ContextCapture is more than cosmetic: licensing moved into Bentley's subscription and consumption model, and existing perpetual users should confirm what a renewal converts to before assuming continuity of cost.
  • Consumption-based entitlements make the cost of a large reconstruction hard to predict in advance, which is awkward when you are quoting a fixed-price deliverable to a client.
  • The desktop engine is Windows only and reconstruction is compute-hungry, so meaningful throughput needs either serious workstation hardware or paid cloud processing.
  • Bentley does not publish a plain rate card and pricing varies by region, reseller and existing agreement, so two firms buying the same thing can pay very different amounts.
  • Value compounds inside the Bentley ecosystem, and a firm whose design work happens in Autodesk or Esri tools pays for a positioning it will not use while getting the same mesh a cheaper standalone photogrammetry package would produce.

Sight Machine

  • Onboarding is a data engineering project measured in months per plant, so value arrives long after the contract starts and the internal sponsor needs the patience and budget to survive that gap.
  • It assumes the instrumentation already exists, so a plant whose machines produce no usable data gets nothing from a data platform and needs to solve connectivity first with a different class of product.
  • Pricing scales with plants and data volume and is never published, which puts it out of reach for single site manufacturers regardless of how relevant the capability sounds.
  • It is not an MES and does not control or execute anything, so it sits on top of the operational systems and adds a layer to maintain rather than replacing one.
  • Success depends on a central team that owns definitions and enforces them, and in groups where plants retain autonomy the standardisation the platform provides gets quietly ignored at site level.

Answered from the vendors’ own pages

Bentley iTwin Capture Modeler: Is ContextCapture discontinued?

The name is. The product continues as iTwin Capture Modeler within Bentley's iTwin family.

Sight Machine: Is this an OEE product?

It can produce OEE, but buying it for OEE alone is expensive. The reason to buy it is cross plant data standardisation.

Bentley iTwin Capture Modeler: Does it still support a perpetual licence?

New buyers should expect subscription or consumption-based entitlements. Confirm the exact conversion path if you hold an older perpetual licence.

Sight Machine: Does it need a historian?

It reads from historians, control systems and MES. Some source of machine data is a prerequisite.

Bentley iTwin Capture Modeler: Can it process laser scan data as well as photographs?

Yes. It fuses point clouds with imagery in a single reconstruction.

Sight Machine: How long does a plant take to onboard?

Plan in months per plant, depending on how many sources and how inconsistent the existing definitions are.

Bentley iTwin Capture Modeler: Do I need other Bentley software to use it?

No, output formats are usable elsewhere, but the commercial and workflow case is strongest if you already run MicroStation or OpenRoads.

Sight Machine: Who is the buyer?

A corporate manufacturing, quality or digital function. It is rarely a plant level purchase.
