Create stunning photorealistic images and videos from any CAD system, real life photo, or even a quick napkin sketch.
IMAGE RENDERS COMPLETE IN 60 SECONDS.
Bella Render is a spectral physically based renderer for prepared 3D scenes, with desktop plugins, a standalone GUI, and command-line rendering. It focuses on realistic light transport, optical effects, layered materials, and render passes for product visualization, architecture, and DCC workflows.
Bella Render is a full spectral renderer: teams work from a Rhino, Maya, SketchUp, imported geometry, or Bella scene, tune materials, lights, cameras, and solvers, then let a progressive render converge. RENDERCAD fits the lighter handoff when the useful input is already a CAD viewport, product image, architectural view, or concept screenshot and the goal is a polished AI render without installing a host plugin or preparing full 3D scene data. Choose Bella when optical realism, caustics, render passes, or CLI automation matter; choose RENDERCAD when speed and low setup from an existing design view matter more.
Bella rewards renderer-operator control. Its workflow can use host plugins, Bella GUI, or Bella CLI, and it exposes spectral materials, layered surfaces, thin film effects, nested dielectrics, complex IOR, physical sky and sun, denoising, render passes, and scene-file automation. That depth is valuable when the deliverable depends on physically grounded light behavior or repeatable production rendering from complete 3D data.
RENDERCAD serves a different moment in the visualization process. Instead of exporting geometry, rebuilding materials, or waiting for a local render setup to converge, a designer can start from the image they already have: a CAD viewport, product angle, architectural screenshot, or design review frame. Use Bella for authored 3D rendering pipelines; use RENDERCAD for fast presentation visuals, design alternatives, and marketing drafts from existing visual inputs.
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 Bella Render
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 image renders complete in 60 seconds. Competing renderer speed depends on scene complexity, render settings, hardware, queue time, and final output quality.
RENDERCAD starts at $9/month with credits that refresh monthly - predictable costs with no upfront investment or perpetual license fees.
RENDERCAD starts from a supported 2D image such as a CAD viewport capture, product photo, or drawing. You do not need to import the native 3D scene, but you may need to capture or export a clear image from the source application first.
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.
Yes. A clear viewport capture can become a more polished visual for a design review. Image renders complete in 60 seconds, making it practical to prepare or iterate presentation options.
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.
Upload a clear view, describe the brushed-aluminum finish you want, and add a material reference when the visual direction matters. Because the result is generated from an image, inspect the grain direction and surface details against your original design before using it in a final presentation.
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.
Start with a clear source view, choose a simple background, and describe the studio look you want. RENDERCAD can generate a presentation image without requiring you to build a traditional light rig, but the lighting is image-based and should be reviewed rather than treated as a physically measured setup.
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.
The Seamless Loop option is designed to improve continuity between the end and beginning of a generated video. Inspect the transition before publishing because generative motion and loop quality can vary by image and model.
