The short version
- Each has a real cost: Arnold the Internet Archive's capture of Autodesk's Arnold overview page on 30 December 2022 stated a subscription can be installed on up to 3 computers or devices, though only the named user may run it on one machine at a time, and includes access to the 3 previous major versions.; 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.
- They diverge on capability: Arnold covers Ray tracing, Bentley iTwin Capture Modeler covers Aerial triangulation.
- 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.
Arnold
- The Internet Archive's capture of Autodesk's Arnold overview page on 30 December 2022 stated a subscription can be installed on up to 3 computers or devices, though only the named user may run it on one machine at a time, and includes access to the 3 previous major versions.
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.

Answered from the vendors’ own pages
Arnold: How much does Autodesk Arnold cost?
Autodesk Arnold pricing is not published on the vendor website. Arnold is available through Autodesk subscription plans or standalone licensing. Customers should contact Autodesk directly for pricing quotes.
SourceBentley iTwin Capture Modeler: Is ContextCapture discontinued?
The name is. The product continues as iTwin Capture Modeler within Bentley's iTwin family.
Arnold: Is Arnold free for educational use?
Yes, Autodesk provides free educational licenses for Arnold to students and educators. Educational access allows learning of professional rendering capabilities at no cost.
SourceBentley 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.
Arnold: What does Arnold render?
Autodesk Arnold is an industry-standard photorealistic rendering engine used for visual effects, animation, and design visualization. It supports GPU and CPU rendering with advanced features for film, television, and product design.
SourceBentley iTwin Capture Modeler: Can it process laser scan data as well as photographs?
Yes. It fuses point clouds with imagery in a single reconstruction.
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.
