Fast AI stills from Katana and Arnold preview screenshots for look reviews.
KtoA plug-in workflow for rendering Katana lighting and lookdev scenes with Autodesk Arnold
KtoA plug-in workflow for rendering Katana lighting and lookdev scenes with Autodesk Arnold
In Katana, frame the asset or shot in the Viewer, Monitor, or Arnold preview render, including the camera angle, lighting rough-in, shader work, material assignments, and any key atmospherics you want preserved. Upload the screenshot to RENDERCAD and generate a polished still for look-review boards, lighting alternatives, and approval images. For API automation, use /developers. Arnold remains the renderer for final frames, AOVs, deep output, Cryptomatte, animation, and pipeline delivery.
Modeled by CADSharp in Onshape. Rendered with RENDERCAD.

| Feature | RENDERCAD | Arnold for Katana (KtoA) |
|---|---|---|
| Engine | Generative AI | Autodesk Arnold Monte Carlo ray tracing renderer inside Katana via KtoA |
| Output | Images + Video | Final rendered frames, image sequences, EXR/AOV passes, and lookdev previews from Katana |
| Resolution | HD / 4K | Defined by Katana and Arnold render settings and camera output |
| Image Speed | ≈10 - 60 Seconds | Scene-dependent CPU or GPU rendering; higher samples, volumes, motion blur, and AOVs can increase render time |
| Video Speed | ≈1 - 5 Minutes | Animation is rendered per frame through Arnold and Katana batch or farm workflows |
| Scene Set Up | Zero | Katana node graph with KtoA render settings, Arnold lights, cameras, shaders, materials, procedurals or USD assets, and AOVs |
| Input | Screen Snip | Katana scenes using KtoA, Arnold nodes, procedurals, USD or asset pipeline inputs, and renderer-specific material networks |
| Hardware | Cloud GPU | Desktop Katana workflow on supported systems with matching KtoA and Arnold builds |
| Install | None | KtoA plug-in installation required; build compatibility depends on the installed Katana and Arnold versions |
| Cost | from $20/mo | Autodesk Arnold licensing and Katana licensing are required for production use; terms vary by region and account type |

Get StartedCommon solutions for Arnold for Katana users
Instead of complex UV mapping, upload your image or use the RENDERCAD overlay tool to snip your screen. Type "Carbon Fiber" in the prompt, select "Exact" style, and in about 10-60 seconds, the AI will retexture your image realistically.
Snap a picture using the RENDERCAD overlay. Select the "Realistic" engine, set Condition to "Clean," and prompt "Brushed Aluminum." The AI applies the texture orientation correctly to your geometry.
Don't struggle with refraction settings. Upload your image or snip your view with RENDERCAD, set Style to "Creative," and prompt "Clear Glass." The engine handles transparency and light bending automatically.
Upload a CAD screenshot, real photo, or hand drawing to RENDERCAD Studio. Add "Cold beverage with condensation" to your custom prompt. The "Realistic" engine will generate realistic droplets on the surface.
Use the RENDERCAD overlay. Prompt for "Injection Molded Plastic" and in Advanced Settings, set Condition to "Clean" for a smooth, factory-fresh look.
You don't need texture maps. Upload your image or snip your screen with RENDERCAD, then set Advanced Settings > Condition to "Dirty" or "Heavily Used" to instantly apply rust and age.
Capture your model and prompt "Oak Wood" in RENDERCAD. The Image-to-Image engine generates a unique, non-repeating grain pattern that fits your object's form.
Upload your image or snip your screen. In RENDERCAD, prompt "Polished Gold" and set Background to "Grey" or "Gradient." The AI generates the necessary reflections to simulate a metallic surface.
No need for bump maps. Use the RENDERCAD overlay to capture the view, then prompt "Black Leather." The AI interprets the depth and stitching automatically.
Capture your screen and use the custom prompt "Glowing Neon Blue Lights." The AI paints the bloom and light spill directly onto your image.
While RENDERCAD generates full rectangular images, you can set the Background to "White" or "Grey" in Advanced Settings for easy masking in post-production.
Upload your image or snip the model, then prompt for "Denim," "Cotton," or "Velvet." RENDERCAD applies the weave texture naturally over the surface.
