The short version

  • Only Corona Renderer has a free tier, so it costs nothing to try first.
  • 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.; Corona Renderer plugs into 3ds Max and Cinema 4D only, so it is not available for Blender, Maya or standalone use
  • They diverge on capability: Bentley iTwin Capture Modeler covers Aerial triangulation, Corona Renderer covers Unbiased rendering.
  • 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.

Corona Renderer

  • Plugs into 3ds Max and Cinema 4D only, so it is not available for Blender, Maya or standalone use
  • Sold by subscription rather than perpetual licence, from $414 a year for Corona Solo
  • Asset library access is metered by tier, at 15,000 assets on Solo against 18,500 on Premium
  • AI credits are capped monthly, at 100 on Solo and 500 on Premium
  • Real-time ray tracing through Vantage requires the Corona Collection tier at $994.80 a year

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.

Corona Renderer: How much does Corona Renderer cost?

Corona Solo is $345/month or $4,140/year (charged monthly). Corona Collection starts at $225/month. Corona Premium is a $110/month add-on to Solo. Educational licenses save up to 80% versus commercial pricing.

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.

Corona Renderer: Does Corona offer a free trial?

Yes, Corona includes a 30-day free trial for both Windows and macOS with full feature access and training resources. A 14-day money-back guarantee is included with all paid plans.

Source
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.

Corona Renderer: What is the difference between Corona Solo and Corona Collection?

Corona Solo ($345/month) is a personal license for single users and includes 100 AI credits monthly. Corona Collection ($225/month) is a floating team license with real-time ray-tracing (Vantage), 4,000+ animated characters, and 1,500 AI credits monthly.

Source
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.

Corona Renderer: Are there per-node render costs?

Yes, Corona offers expandable render nodes at separate pricing. Additionally, Chaos AI credits can be purchased on a pay-as-you-go basis beyond monthly allowances.
