Fast AI stills from Houdini, Solaris, and Arnold preview captures before final HtoA renders.
HtoA plugin workflow for Arnold rendering in Houdini, Solaris USD, Arnold ROP, and AOV review
HtoA plugin workflow for Arnold rendering in Houdini, Solaris USD, Arnold ROP, and AOV review
In Houdini, frame the model, FX cache, groom, set, lighting test, or Solaris USD stage from the viewport, render camera, Arnold IPR, or Hydra delegate view. Hide interface clutter, keep material and silhouette cues readable, and upload the screenshot to RENDERCAD to generate a polished look target for review boards, lighting options, client feedback, and pitch imagery. Keep Arnold for final sampling, motion blur, volumes, Cryptomatte, EXR/AOV passes, frame ranges, and pipeline delivery; use RENDERCAD when the team needs a fast still before deep HtoA setup. For API automation, use /developers.
Modeled by CADSharp in Onshape. Rendered with RENDERCAD.

Tired of keeping up with the latest gen AI models? RENDERCAD is powered by a proprietary ensemble of the most cutting-edge AI engines, always up to date and fine-tuned to strictly maintain your design intent.
| Feature | RENDERCAD | Arnold for Houdini (HtoA) |
|---|---|---|
| Engine | Generative AI | Autodesk Arnold Monte Carlo ray tracing renderer inside Houdini through HtoA, with CPU and GPU rendering modes |
| Output | Images + Video | Still images, frame sequences, Arnold Render View previews, AOVs, and common formats such as EXR, PNG, JPEG, and TIFF |
| Resolution | HD / 4K | Defined by the Houdini camera, Arnold ROP, or Solaris render settings and constrained by scene complexity, hardware, and memory |
| Image Speed | ≈10 - 60 Seconds | Scene-dependent rendering; higher samples, volumes, motion blur, displacement, hair, and many AOVs can increase render time |
| Video Speed | ≈1 - 5 Minutes | Animation renders frame by frame through Arnold, husk, batch, queue, or render farm workflows |
| Scene Set Up | Zero | Houdini or Solaris scene with HtoA loaded, Arnold-compatible shaders, lights, cameras, render settings, denoising, and AOVs |
| Input | Screen Snip | Houdini scenes rendered through HtoA, Arnold ROPs, Arnold IPR, Solaris/USD workflows, or the Arnold Hydra render delegate |
| Hardware | Cloud GPU | Desktop Houdini workflow on systems supported by Houdini and Arnold; GPU rendering depends on supported hardware |
| Install | None | HtoA plugin installation required; the HtoA build must match the Houdini build and platform |
| Cost | from $20/mo | Autodesk Arnold subscription or license required for production rendering; terms vary by region and account type |

Get StartedCommon solutions for Arnold for Houdini 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.
