ROTONIX PRO 3.1.v1 — Guide and purchase link
ROTONIX PRO is an AI matte assistant for Foundry Nuke, created by Bishal Pandit. This small Nukepedia download contains the user guide, terms, privacy notice and official purchase link; it does not contain Setup.exe. The full Windows installer (approximately 3.7 GB, with model weights included) is downloadable from Gumroad after purchase. A public Pro trial installer link is pending. Contact [email protected] for trial-download enquiries before purchasing. This is separate from the existing free ROTONIX Public Beta.
Trial and purchase
The full-feature trial starts automatically on first use on a PC, with no payment or activation key during those 10 days. After expiry, a paid licence is required. The price is ₹999 once for lifetime access on one active PC, including future Pro updates. Purchase through the Gumroad page linked below, then copy the receipt licence key into ROTONIX PRO → Licence → Activate lifetime access. Paid access refreshes online automatically, with up to 72 hours offline. Ordinary reinstalls retain the original trial expiry.
Features
SAM 3.1 primary masks, optional text selection, and combined bounding-box/positive/negative-point selection. Pro Detail combines BiRefNet HR with ViTMatte Base refinement. Includes paint and eraser corrections, separate objects, forward/backward tracking with live previews, motion-aware temporal stabilization, timeline playback and correction-frame jumps. Set your work range, cache that range explicitly, and export it as a source-resolution black-and-white RGBA EXR sequence through one Nuke Read node. Hardware settings and GPU-memory recovery are automatic. Footage stays on your PC.
Install
1. Save your work and close Nuke.
2. Download and run ROTONIX-PRO-3.1.v1-Setup.exe. Read and agree to the application terms, bundled model agreements and privacy notice.
3. Keep the automatic hardware option and choose your Nuke startup folder. Allow at least 20 GB free storage plus room for caches.
4. Let AI preparation finish. Model weights are included; first-time private runtime library downloads require internet. No manual model download or Hugging Face account is needed for this bundle.
5. Restart Nuke and open ROTONIX PRO → AI Matte Assistant. The trial begins when you first use the tool.
Your first matte
Select an image-producing node and click Use Selected. Review the footage, set the working range and click Cache Work Range. Add points, a box or a short text prompt; correct the matte with paint/eraser. Track forward/backward, review the final stabilized result and click Create Matte Sequence. Export includes only your working range. Mouse wheel zooms directly; middle mouse/Space-drag pans; Ctrl+wheel adjusts brush size.
Requirements and validation
Windows 10/11 x64. Nuke 15–17.1 is the compatibility target. Native export was verified on Nuke 17.1; interface checks passed with Qt 5/6. Please validate Nuke 15/16 and your own hardware during the trial. NVIDIA CUDA provides the best speed; smaller GPUs and CPU-only systems use slower automatic fallbacks. Nuke and your GPU driver are installed separately. Results depend on footage and hardware, and artist corrections may be needed. Review hair, motion blur and transparency on your actual shots.
Purchase policy
Test compatibility, performance and all features during the trial before purchasing. Digital purchases are non-refundable except where required by law or Gumroad policies. Purchase the one-time ₹999 lifetime licence through the creator’s linked Gumroad page. Test all features during the trial before buying.
