Chaos is not monkeying around when it comes to Veras, its architecture-guided AI rendering engine.The just-released Veras 4.0 is now powered by Google’s image-generation model,Nano Banana Pro. Designed to deliver higher-fidelity designs with fewer visual errors, the new engine significantly improves how Veras understands geometry, lighting, and materials, says Chaos. This will result in more creative and reliable outputs as architects explore design options coming in from Revit, SketchUp, or Rhino. 

Chaos’ Veras 4.0 AI-powered visualization tool for the AEC industry is totally bananas. Veras is an image-to-video-generation tool for the Chaos AI ecosystem that can turn any render into a short video. Serving as an extension of the user’s CAD tools, it transforms sketches, 2D images, and 3D models into renderings and animations quickly and easily for instant visual feedback. Because Veras understands architectural intent, there’s no need for expert prompting, says Chaos. And now, the tool is even more advanced, powered by Nano Banana Pro, Google’s advanced image-generation model.

With this update, Chaos peels away past limitations resulting from the Veras 3 engine version, which was Stable Diffusion-based, making Veras more predictable and versatile, according to Chaos. Veras 4 delivers higher fidelity, fewer visual errors, and more reliable design output, the company says, and significantly improves how Veras understands geometry, lighting, and materials. The result is cleaner, more consistent images that better reflect the designer’s intent, Chaos contends.

The Nano Banana–powered engine also unlocks new workflows that were not previously possible in Veras, from turning 2D plans, drawings, or even hand-sketched images into 3D scenes, to creating interiors from mood boards and producing multi-angle perspectives that retain correct geometry. Furthermore, designers can add people/characters or furniture with a single prompt, or make changes without selecting objects individually. These capabilities remove many of the manual steps that once slowed early-stage design exploration. 

Veras 4.0 also gives designers stronger control over prompts. Instead of treating prompts as loose suggestions, the new engine interprets them as clear instructions, producing outputs that more closely follow the intended style, material changes, or environmental adjustments.

Veras 4.0 is built for architectural or interior designers who need fast, design-faithful visuals directly from SketchUp, Revit, or Rhino, without having to be rendering experts, says Chaos. It introduces practical improvements, like Image Reference as Input,allowing designers to guide new outputs using an existing image instead of relying on text, and Gallery Mode, a grid-based thumbnail view of all past renders, making it easier to compare variations over time. Twelve new video presets have also been added, giving designers ready-to-use settings for animation. Teams can now produce smooth, photorealistic motion with balanced lighting and a consistent, cinematic style, while reducing setup time.

Veras originally was the flagship app from EvolveLab, which became part of Chaos early last year.

Veras 4.0 is available now as a stand-alone product, with both annual and monthly subscriptions. It is also available within the Enscape Premium and ArchDesign Collection suites.
