How to Share and Review Files with CLO Viewer

How to Share and Review Files with CLO ViewerCLO Viewer is a free, lightweight companion to CLO 3D designed specifically for viewing, sharing, and reviewing 3D garment files without needing a full CLO 3D license. Whether you’re a designer collaborating with a client, a pattern-maker checking fit, or a merchandiser approving styles, CLO Viewer streamlines communication by letting reviewers inspect 3D garments, view fabric and trim details, and leave feedback. This article walks through the full process of preparing files, sharing them securely, reviewing in the Viewer, collecting feedback, and using best practices to keep collaboration smooth and efficient.

What CLO Viewer does (and what it doesn’t)

• CLO Viewer lets users open and interact with .zprj/.zpac and other CLO-exported files, view layers, measure dimensions, and playback animation.
• It does not allow full editing of patterns, grading, or advanced simulation setup — those require CLO 3D.
• Ideal uses include client reviews, tech-pack checks, internal approvals, and remote fittings.

Preparing files in CLO 3D for sharing

Before sending anything to reviewers who will use CLO Viewer, prepare a clean, organized file from CLO 3D:

1. Organize scenes and avatars

   • Remove unused avatars and save a scene with only the avatar(s) needed for review.
   • Use standardized avatar names and sizes to avoid confusion.

2. Clean up layers and materials

   • Consolidate unnecessary layers and label material properties clearly.
   • If multiple fabric options exist, create separate scenes or use scene variations.

3. Set cameras and animations

   • Create and save camera angles that highlight crucial details (front, back, side, close-ups).
   • If motion or drape over time matters, record an animation timeline for reviewers.

4. Lock or hide editable pattern pieces (optional)

   • If you want to prevent accidental edits by reviewers using more advanced tools, hide or lock pattern pieces and save a non-editable export.

5. Export formats compatible with CLO Viewer

   • Export as .zprj (CLO project) or .zpac (package) so materials, avatars, and animations remain intact.
   • For broader compatibility or simpler reviews, export turntable videos or static high-resolution renders.

Example: Export a .zpac package including the project, avatars, texture maps, and a short animation that rotates the model 360°.

Methods to share CLO Viewer files

Choose the method based on recipient technical comfort, security needs, and file size.

1. Cloud storage links (recommended for large files)

   • Use Dropbox, Google Drive, OneDrive, or internal company storage.
   • Set link permissions: view-only for external stakeholders; restrict to specific emails where possible.
   • Include a short README with viewing instructions and which cameras/animations to check.

2. Direct email (for small files)

   • Attach .zprj/.zpac if under attachment size limits.
   • Compress into a .zip if needed.

3. Company PIM/PLM or product lifecycle platforms

   • Upload packages to your product management system for version control and traceability.

4. Collaboration platforms (Slack, Teams)

   • Good for quick delivery and discussion threads; include the file and pinned instructions.

5. CLO Cloud (if using CLO’s cloud services)

   • Upload projects to CLO Cloud to share directly with Viewer users via project links.

How reviewers open files in CLO Viewer

1. Install CLO Viewer

   • Viewer is free and available for Windows and macOS; ensure recipients download the correct version.

2. Open the file

   • Use File > Open and select the .zprj/.zpac package.
   • If shared via cloud link, download the package first, then open in Viewer.

3. Navigate the interface

   • Use the 3D viewport to rotate, pan, and zoom.
   • Switch between saved cameras or use orbit controls to inspect the garment.
   • Toggle shadows and lighting to check drape and surface detail.

4. Playback animations

   • Use the timeline to play recorded animations, step through frames, or scrub to specific moments.

5. View layers and materials

   • Open the Object or Property panels to check fabric assignments, trims, and material maps.
   • Toggle visibility of individual garment pieces or accessory items.

6. Measurement and inspection tools

   • Use the measurement tool to confirm key dimensions and fit points.
   • Check seams, pleats, and overlap areas by zooming and changing camera angles.

Leaving feedback and annotations

CLO Viewer offers basic tools for reviewers to communicate findings. Combine built-in options with external tools for structured feedback.

1. Notes & screenshots

   • Take screenshots directly from the Viewer (use built-in export or OS-level screenshot).
   • Annotate screenshots with arrows and notes using image editors, or attach them to comments in your collaboration platform.

2. Timestamped feedback for animations

   • Note the frame/time in the animation where an issue appears (e.g., “Frame 0:42 — sleeve collision at underarm”).

3. Structured comment sheets

   • Provide a tech checklist: fabric, grainline, seam allowance, trim specs, measurements, and requested fixes.
   • Use a shared spreadsheet or PLM comment fields to track issues, owners, and status.

4. Versioning

   • Ask reviewers to include the file name and version in each comment (e.g., Product_X_v03.zpac).
   • Keep a changelog in the project folder.

Best practices for efficient review cycles

• Provide a single source of truth: an organized folder with the .zpac, reference images, spec sheet, and a review checklist.
• Keep files lightweight: remove unnecessary high-resolution textures if only fit/drape is being reviewed.
• Use naming conventions: style_SKU_size_version (e.g., ALPHA_SKU123_M_v02.zpac).
• Set clear deadlines and required deliverables from reviewers (e.g., “Approve/reject with comments within 48 hours”).
• Train key stakeholders on basic Viewer controls — a 5-minute screencast saves time later.

Troubleshooting common issues

• Cannot open file: ensure file extension is .zprj or .zpac and Viewer version matches the file’s export version.
• Missing textures: confirm texture paths are included in the package (.zpac preferred) or re-export with embedded textures.
• Animation not playing: check timeline export from CLO 3D and that the animation is included in the package.
• Performance lag: reduce viewport quality or close other apps; reviewers on low-spec machines may prefer static renders.

Security and confidentiality tips

• Use password-protected cloud links or share within a secure PLM for sensitive IP.
• Limit access duration on shared links.
• For critical approvals, require reviewers to sign an NDA before sharing detailed project files.

Example workflow (concise)

1. Designer prepares scene in CLO 3D, saves cameras and exports a .zpac with embedded textures and a 360° animation.
2. Upload .zpac to company cloud, set link to view-only and expiry in 30 days.
3. Send link with a one-page review checklist and requested deadline.
4. Reviewers open in CLO Viewer, take annotated screenshots, and submit comments in the shared spreadsheet referencing frame numbers.
5. Designer updates the file, increments version, and repeats the cycle until approval.

Sharing and reviewing with CLO Viewer reduces friction between design and non-design stakeholders by letting everyone interact with 3D garments without specialized software. With clear file prep, structured feedback, and simple naming/versioning rules, you can speed approvals and minimize miscommunication.
