| Approach | Architect-native rendering workbenchCreate, Enhance and Edit share one project workspace. | Model-aware visualization inside design tools[1][7]A standalone web app is also available. |
| AI brief and prompt guidance | Free brief check on SendClarify an ambiguous render with suggested replies or your own answer. You can also choose Skip and Send Now. | Image-to-prompt starter[4]Start from a sketch or image, then add a prompt or choose a preconfigured Preset. |
| Generate persistent project settings | Yes, one Composition per projectComposition = Style + Scene + Lighting + Materials + Entourage. Full text-to-all-fields runs during new-project setup. Later, a Project reference image can Generate Composition. Each field can generate from words or images at any time. | No generated brief confirmed[5][10]Veras saves render settings and reusable Presets. It does not document a generated structured project brief. |
| Reuse one visual direction across studies | Yes, across every studyAll studies share the same project settings, Project reference image, and applied Preset. | Presets and Design Lock[4][9]Save and reuse prompt-setting combinations. Design Lock carries architectural language across views. |
| Parallel generation and Variations | Parallel generation at send and laterMultiple images can run in parallel from Composer. Multiple Variations can run later from any finished render. | Up to four simultaneous images[5]Veras can render multiple images at once and queue further variations. |
| Supported resolutions | 512, 1K, 2K, 4K [1] | 1K, 2K, and 4K[5]The Veras output Resolution selector lists these three sizes. |
| Supported aspect ratios | 1:1, 1:4, 1:8, 2:3, 3:2, 3:4, 4:1, 4:3, 4:5, 5:4, 8:1, 9:16, 16:9, 21:9 [1] | Aspect selector; exact list unpublished[5]Chaos documents an Aspect selector but does not publish its complete ratio list. |
| Supported quality levels | Low, Medium, High [1] | Render engine tiers[5]Engines trade quality, speed, cost, editing, and retention; they are not simple quality levels. |
| Works from a screenshot, any 3D tool | YesStarts from screenshots from Rhino, SketchUp, Blender, Revit and other 3D tools. | Yes[1][10]The web app accepts images and sketches. Plugins read an active model view. |
| Built-in 3D model workflow | Upload → clay viewer → Capture → EnhanceUpload a supported 3D/CAD model package, inspect clay geometry, set camera and visibility, save a Viewer capture, use it as Enhance source. | Model-aware host integrations[4][7]Works inside supported authoring tools and from images. A standalone browser clay-viewer and capture chain is not documented. |
| Source constraint and review | Source-guidedEnhance keeps the source camera, framing, angle and dimensions. Review proportions and openings in every generated result. | Model-aware and source-guided[10][11]Host workflows use camera, geometry, and material context. Generated details still require professional review. |
| Region edit | Yes, Edit modeMark multiple named regions with Rectangle or Brush. Use Eraser to refine them, then change only those areas. | Yes, Smart Selection[8][10]Select by object, material, category, or prompt, then apply Modify or Replace. |
| Built-in post-render image operations | 56 one-click image operationsModify, Relight, and Effects reuse the source Render model, settings, and Composition snapshot. Each result has the normal per-image model charge. | Presets, Smart Selection, Modify and Replace[4][8][10]Preset and selection-led edits cover image refinement without one categorized post-render operation catalog. |
| Built-in Preset system | 60+ built-in PresetsApply a built-in Preset, use a Project reference image, or save versioned Presets. | Yes[1][10]Includes presets and typed Style, Material, Color, Object, Design Lock, and Custom references. |
| Free 4K upscale | Yes, free Lanczos 4K | Not confirmed as free[1][3]The reviewed Veras plan pages do not state a free 4K upscale. |
| Renders survive tab close | YesServer-side render jobs continue after the browser tab closes. | Not publicly confirmed[10]Veras stores completed renders with settings. Public pages do not confirm in-progress recovery after tab close. |
| Models | Nano Banana 2, Nano Banana Pro, Nano Banana, and GPT Image 2Choose a model per render. | Nano Banana 2, Stable Diffusion, WAN 2.2[1][11]Chaos identifies these models for Veras image and video work. |
| Free to try | Yes, no credit cardYour first renders are free. | 14-day trial[2]Payment starts automatically after the trial unless canceled in time. |
| Native plugin | NoUse a browser screenshot from the 3D tool you already work in. | Yes[1][7]Direct CAD and BIM plugins plus integrations in Enscape, V-Ray, and Corona. |
[1] Options depend on the selected model. Aspect ratio is Create-only. Quality is available on GPT Image 2.

Browser workbench or direct model connection
Choose CAD Scene when
Architects who want one browser workspace across screenshots, models, studies, and precise region edits.
Choose Chaos Veras when
Architects who want camera-aware rendering inside CAD, BIM, Enscape, V-Ray, or Corona.
Where CAD Scene fits
CAD Scene keeps the rendering process in one browser workspace. A screenshot from any 3D tool is enough to begin.
Create, Enhance, and Edit share project context. Named regions make local changes explicit and reviewable.
Choose CAD Scene when your studio uses several modeling tools. It avoids plugin deployment and host-version checks.
One-click image operations replay common refinements from the finished Render and its stored context.
- One project holds studies, source images, settings, presets, and render history.
- Each render can use a different available image model.
- Free Lanczos 4K upscale and durable server-side render jobs are included.
Where Chaos Veras fits
Veras by Chaos has the stronger direct connection to model context. Its plugins read active-view geometry, camera, and materials.
Smart Selection can use host object and material IDs. That makes a façade or finish easier to isolate without painting a mask.
Typed references clarify how each image should influence a result. Design Lock carries detailing language across views.
Veras also covers image-to-video, video combining, and shareable galleries. Those are material advantages for presentations.
- Direct workflows for major CAD, BIM, and Chaos rendering tools.
- Model-aware selections and camera-synced viewport capture.
- Built-in video generation and presentation sharing.
Chaos Veras pricing
As reviewed on July 23, 2026, the UK page lists Starter at £168 yearly, or £14 monthly effective, before tax. It includes 500 monthly credits.
Chaos localizes prices by region and currency. Confirm the annual checkout total for the purchasing entity.
The 14-day trial starts paid annual billing automatically. Cancel at least one day before it ends to avoid conversion.
Chaos also bundles Veras access with parts of its renderer lineup. Check the current license route before buying standalone.
Test the model connection, not just the first image
Use one approved camera and one difficult material junction. Generate three variations in each tool.
In Veras, test a host-integrated view and a Smart Selection edit. Then test Design Lock on a second camera.
In CAD Scene, test Enhance, a named-region Edit, and a model change. Close the tab during one render.
Compare openings, edge alignment, repeated elements, and material boundaries. Treat vendor speed and fidelity statements as claims, not acceptance criteria.
