KeyShot for ZBrush is a ZBrush-focused visualization workflow built around the ZBrush to KeyShot Bridge. From ZBrush, an artist can enable KeyShot as the external renderer and use a BPR render to send the visible sculpt scene into KeyShot Studio. The handoff can carry SubTools, Polypaint, textures, and other visible scene data, then KeyShot becomes the place to refine materials, environments, lighting, camera, and final render settings. It suits character sculpts, collectibles, concept maquettes, and product forms that need a deliberately art-directed presentation.
KeyShot for ZBrush is strongest for a sculptor who wants a connected desktop rendering workflow: send the visible ZBrush scene into KeyShot, keep refining the sculpt, and update the KeyShot scene while developing materials, lighting, and presentation. RENDERCAD is a useful alternative when the immediate need is to explore polished render directions from a well-composed ZBrush viewport, turntable frame, CAD view, or product reference image. It can help test a studio-product, collectible, or marketing visual direction without first constructing a dedicated KeyShot scene. Use KeyShot when repeatable scene control and render settings are the priority; use RENDERCAD for fast visual exploration and image-led iteration.
A practical KeyShot for ZBrush workflow starts by preparing the visible SubTools and view in ZBrush, enabling KeyShot as the external renderer, then sending the scene with BPR. In KeyShot Studio, the artist can assign rendering materials, adjust the environment and lights, frame the shot, and produce a final still or animation. Subsequent ZBrush changes can be sent back into the KeyShot scene, which makes the workflow valuable when the sculpt remains in progress. It is especially appropriate when the result must be repeatable from a maintained 3D scene rather than interpreted from an image. RENDERCAD can instead begin with a clean ZBrush viewport or other design image that clearly shows the silhouette, camera angle, major surface breaks, and intended subject. Use it to generate presentation options for reviews, concept boards, product exploration, or marketing mockups, then return to ZBrush or KeyShot for source-controlled work. The boundary matters: an image-based render direction is not a replacement for a KeyShot scene when exact geometry, transferred materials, camera matching, or deterministic revisions are required. For implementation details in an automated RENDERCAD workflow, see RENDERCAD developer documentation.
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.
Modeled by CADSharp in Onshape. Rendered with RENDERCAD.
Add, change, or remove referenced objects with the stroke of a brush.
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 and this workflow
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.
