V-Ray Tip: V-Ray Render Stamp for Traceable, Reproducible Frames

Use the Render Stamp to make every frame traceable to its exact scene state, so reviews, approvals, and rerenders stay bulletproof.

• What it is: a small text overlay generated by V-Ray that can include dynamic tokens for scene, camera, frame, resolution, render time, and more.
• Why it matters: when clients ask for a tweak weeks later, the stamp tells you exactly which file, camera, and settings produced the approved image.

Set it up (universal workflow)

• Open the V-Ray Frame Buffer settings and enable Render Stamp.
• Edit the stamp string to include tokens provided by your DCC integration (consult the built-in token help to see the exact list for your host app).
• Choose placement, font size, and color that are readable yet discreet.
• Save this as part of your studio template or render preset.

Recommended stamp template

Use a compact, human-friendly line that covers the essentials without cluttering the image:

%scene | %camera | F%frame | %w x %h | %rendertime | %date %time | %vrayversion

• %scene: identifies the project/shot or master file.
• %camera: locks the view used at approval.
• %frame: frames for animation or turntables.
• %w x %h: resolution for delivery parity.
• %rendertime: quick health check for performance regressions.
• %date %time and %vrayversion: critical for reproducing results after upgrades.

Best practices

• Keep it single-line to avoid covering content; place it in a consistent corner (typically bottom-left).
• Mirror the stamp string in your render job metadata or shot tracking notes for redundancy.
• For finals, render two outputs: a clean plate and a stamped version for archiving and QC.
• Adopt a naming convention that echoes the stamp (project_shot_task_version_cam_frame.ext) to survive recrops and re-encodes.
• Version-lock: when rolling V-Ray or plugin updates, rely on the stamp to verify identical builds across artists and render nodes.

Pipeline tips

• Include a job ID or ticket number as free text at the end of the stamp for fast cross-reference with production tools.
• For distributed rendering and farm audits, add tokens that expose host/user if available in your DCC.
• On reviews, ask for feedback tied to the stamped frame so notes map cleanly back to a reproducible state.

Troubleshooting

• If the stamp becomes unreadable, slightly increase font size or add subtle shadow/outline if offered by your host.
• If the stamp gets cropped during comp, add a small overscan to finals or store a stamped reference alongside the clean EXR.
