IMAGE RENDERS COMPLETE IN 60 SECONDS.
Chaos Corona is a CPU-based photorealistic renderer for 3ds Max and Cinema 4D, widely suited to architectural visualization scenes that need detailed materials, lighting, scattering, and post-production controls.
Chaos Corona is built for artists who want full control inside 3ds Max or Cinema 4D: physical materials, LightMix-style relighting, Chaos assets, scattering, render elements, denoising, and production-quality still or animation output. That depth is valuable for archviz teams, but it also means the model has to live in a supported DCC scene with prepared materials, cameras, lights, and enough local CPU and memory headroom. RENDERCAD is a better fit when the source is a CAD viewport, concept model, product angle, or design screenshot that needs a polished visual quickly without rebuilding the scene in Max or Cinema 4D. Corona is the deeper renderer for final DCC shots; RENDERCAD is the faster cross-tool path from existing design imagery to presentation-ready render output.
Chaos Corona is a strong fit for architectural visualization specialists working inside Autodesk 3ds Max or Maxon Cinema 4D. Its workflow centers on preparing a full 3D scene, assigning Corona Physical Materials or library materials, tuning camera and lighting, using interactive rendering for feedback, and producing final images or frame sequences with render elements for post-production.
The tradeoff is pipeline commitment. Corona rendering is CPU-based, with optional GPU-assisted denoising and upscaling features, so final output depends on local workstation resources or a separate render setup. CAD users outside 3ds Max and Cinema 4D generally need an export, conversion, or rebuild step before they can take advantage of Corona's material, light, scattering, and pass controls.
RENDERCAD serves a different workflow. Instead of installing a renderer plugin and converting the design into a production DCC scene, a user can start from a viewport screenshot or design image and generate a more polished visual in the browser. That makes RENDERCAD useful for proposals, reviews, product concepts, and quick client-facing views where speed and CAD-tool flexibility matter more than per-material render control.
Choose Corona when the deliverable requires hands-on scene setup, physically based materials, post passes, animation workflows, and close control inside 3ds Max or Cinema 4D. Choose RENDERCAD when the starting point is already visible in a CAD or design viewport and the goal is fast render output without changing the modeling pipeline.
Screenshot the CAD viewport you already have, render in the browser, and download a client-ready still or video without exports, plugins, or GPU setup.

RENDERCAD uses a maintained selection of image-generation models for different rendering tasks. Results can vary by model and input, so compare generated output with the source design before relying on geometry, materials, or dimensions.

Get StartedCommon questions about RENDERCAD vs Chaos Corona
Yes. Request a golden-hour look and describe the mood or direction you want. The generated warmth, shadows, and light direction can vary between results, so compare important design details with the source image.
Describe an environment such as a sunny forest or urban street and use a reference image when needed. Image renders complete in 60 seconds without building a local scene file or environment map.
RENDERCAD's Create Video workflow generates a video from a single image and provides Camera and Product Motion controls. Videos complete in 2-5 minutes.
RENDERCAD can generate orbit-style motion from a single image using a Camera option. Because the motion is inferred rather than rendered from a complete 3D model, review geometry and hidden-side details before publishing the result.
Usually. Generation runs in the cloud, so it does not occupy a local renderer. Keep the relevant browser workflow available as required, and expect normal network and browser resource use while the job is submitted and results are loaded.
RENDERCAD processes generation in the cloud, so it does not require a dedicated local rendering GPU. You still need a supported browser and internet connection, and normal browser, upload, and download activity can use local device resources.
RENDERCAD avoids much of the scene, shader, and local-renderer setup used by traditional rendering tools. Users still need to prepare a useful source image, choose suitable options, describe the intended result, and review generated details.
RENDERCAD starts at $9/month with credits that refresh monthly - predictable costs with no upfront investment or perpetual license fees.
RENDERCAD is designed to create more polished, realistic-looking presentation images from a source view. Results vary by input and settings, and generated images should be checked against the original model before they are used to communicate exact design details.
RENDERCAD can generate a visual interpretation of a described or referenced material without requiring shader parameters. It does not guarantee physically measured or specification-accurate material behavior, so validate critical color, grain, reflectivity, and finish details against approved references.
Describe the wood species and finish you want, and provide a reference image when scale or grain direction matters. RENDERCAD can generate a wood-like visual treatment, but it does not replace model-level texture mapping or guarantee an exact, repeatable grain pattern.
With RENDERCAD, upload or snip a clear image, describe carbon fiber, and add a material reference when exact visual direction matters. Image renders complete in 60 seconds.
