ROTONIX PRO 3.1.v1 — Free 10-day trial
Try ROTONIX PRO on your own footage before buying. Download the full Windows installer and user guide free from the official Google Drive release folder:
https://drive.google.com/drive/folders/1XqQb7aA6vPNFpDj30L46q4D-ejz0RR8s
Download ROTONIX-PRO-3.1.v1-Setup.exe (about 3.7 GB) from that folder. The small Nukepedia ZIP contains the download shortcut, quick-start instructions, user guide, terms, privacy notice and third-party notices; it does not contain Setup.exe. No purchase is required to download and try Pro. This release is separate from the existing free ROTONIX Public Beta.
Automatic trial and lifetime purchase
The full-feature trial starts automatically when you first use ROTONIX PRO on your PC. No payment, email signup or activation key is required during the 10-day trial. Installing alone does not start the trial. Ordinary reinstalling retains the original expiry. After the trial, purchase once for ₹999 for lifetime access on one active PC, including future Pro updates. There is no subscription.

After purchase, open View content in your Gumroad receipt and copy your licence key into ROTONIX PRO → Licence → Activate lifetime access. Paid access refreshes online automatically, with up to 72 hours offline. Deactivate before changing PCs; an existing offline lease can delay transfer by up to 72 hours.
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 and start
1. Download Setup.exe and the guide from the linked Google Drive folder.
2. Save your work and close Nuke. Run the installer and read the application terms, bundled model agreements and privacy notice.
3. Keep automatic hardware settings 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. Your trial starts on first use.
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. Read USER_GUIDE.html for the full workflow and troubleshooting.
Requirements and evaluation
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; artist corrections may be needed. Review hair, motion blur and transparency on your actual shots.
Test before buying
Evaluate your actual shots, hardware compatibility, speed and all features during the full-feature trial. Digital purchases are non-refundable except where required by law or Gumroad policies. Gumroad checkout shows the final currency conversion and any applicable taxes.
