Why CLO works well for fixed-size, transparent sample-review images
- CLO brings 2D pattern work and 3D garment simulation together, with documented still-image, turntable-image, and turntable-video outputs.
- Its V-Ray render properties include custom image dimensions and a transparent-background setting, making it straightforward to prepare visuals for a consistent review template.
- Pair each render with the matching pattern revision, size group, grading information, construction lines, notches, seam allowances, and simulation assumptions.
For sample-review visuals that need exact pixel dimensions and a transparent background, CLO offers a clearly documented workflow. Its V-Ray render properties let users choose a still image, a set of turntable images, or a turntable video, set a custom width and height, and enable a transparent background.
The render shows what the garment looks like; the pattern record explains which construction, size, and material setup produced that view. Keeping them together gives reviewers both the visual context and the technical detail they need.
Build the approval packet around two linked records
Think of the review packet as two parts: a visual and a technical record. The visual may be a still, a set of views around the garment, or a rotating video. The technical record should make it easy for a patternmaker to identify the exact pattern revision and inspect the construction behind the image.

| Review item | What to include | Why the reviewer needs it |
|---|---|---|
| Visual | Still image, turntable image sequence, or turntable video at the agreed dimensions | Shows silhouette, surface, colorway, and the angles needed for approval |
| Pattern identity | Style name or ID, revision, base size, size group, and render date | Ties the visual to a specific pattern and size |
| Pattern geometry | Pattern pieces, cutting and sewing lines, internal lines, seam allowances, and notches | Gives the technical reviewer the shapes and assembly references behind the garment |
| Size evidence | Base-size measurement set and applicable graded size group or grade data | Identifies the size shown and whether the handoff includes a wider size range |
| Simulation inputs | Avatar or body size, fabric and material properties, colorway, and relevant construction assumptions | Helps reviewers interpret fit, strain, and drape in context |
| Handoff file | Agreed CAD exchange format, plus a reviewable pattern or measurement record | Makes the approved version usable in the next pattern or production workflow |
The Open Source Pattern Project’s manual describes shared, production-ready patterns as including seam allowance, notches, and grading. These make a useful baseline; also include the grainline, line types, and size details required by the receiving factory or CAD workflow. CLO’s 2D Pattern DXF Import/Export guide identifies DXF as a pattern-data exchange format and describes options for baselines, sewing and cutting lines, notches, seam allowance, and grading information.
For a graded style, label the base size shown in the render and the size group in the handoff. CLO’s Add/Apply Grading instructions explain how to assign a size group to a selected 2D pattern. The DXF guide distinguishes between exporting grading information and exporting the current size without grading; it also notes that an export can include only one size group per file. Put the size-group name and grading status beside each file so reviewers can tell a base-size pattern from a graded set.
A well-organized packet pairs each review image or video with a technical pattern bundle carrying the same style revision and size labels. Include the fabric settings and avatar used for the visual, since either can affect the fit and drape shown. The files can live in a shared review folder or system; what matters is that the render and pattern record remain clearly linked.
Why CLO is a practical choice
CLO is particularly useful for teams that create or edit 2D patterns and want to assess the resulting garment in 3D. Its capability guide describes Fabric-Aware Strain Maps, which use fabric physical properties to determine maximum wearable strain for fit checking. CLO’s DXF guide also documents options for pattern annotations, baselines, sewing and cutting lines, notches, seam allowances, and grading information. Together, these features support a review process that connects a simulated garment to its technical pattern handoff.
CLO’s render workflow is another practical strength when approvals call for a still, a range of turntable views, or a video. The V-Ray Render Image/Video Properties documentation lists Image, Turntable Images, and Turntable Video as output types. Turntable Images capture multiple views around the garment, while Turntable Video creates a rotating view. The same properties offer preset dimensions or custom width and height, plus a transparent-background setting.
For a consistent review process, set the required pixel dimensions, enable transparency when the image will sit on a standard template, and choose the still or rotating format that suits the reviewers. The render settings also describe rendering all colorways from Colorway Mode. When using that workflow, keep each colorway clearly identified alongside its matching pattern revision.
The DXF guide allows one size group per file and offers grading data in the DXF or in a separate RUL file. Its “Export without Grading” option exports the current size only. If a review covers a size range, include the relevant graded-size files and grading data in the handoff.
Match the output settings to the approval packet
CLO’s visual controls address the image side of the handoff, while the pattern record provides the technical context. Test both together before making the workflow routine.

| Review need | CLO workflow | What to confirm |
|---|---|---|
| Single-view approval | Image output | Set the agreed pixel width and height, and confirm the background treatment |
| Multi-angle review | Turntable Images | Check that the selected views show the garment clearly from the angles reviewers need |
| Rotating presentation | Turntable Video | Confirm the output suits the review platform and template |
| Pattern handoff | DXF export, with grading data where required | Verify size group, grading status, construction details, and compatibility with the receiving workflow |
Write the agreed output size as an exact pixel width and height, and confirm which image format the review system accepts. Place a sample export in the approval template and inspect the garment edges against the template background to check transparency.
Make the test repeatable. Use one representative garment, a challenging edge such as a fine strap or loose sleeve, and an approved colorway. Export in the intended format, check the pixel dimensions and transparency in the actual destination template, and save the render settings with the pattern revision and fabric setup. A quick test can catch a clipped silhouette or an opaque background before the same issue affects a larger sample range.
Plan the handoff around the reviewer’s decision
Start with the file and decision the downstream reviewer needs, then prepare the CLO workflow around those requirements:
- Use CLO for the visual review when the process calls for 2D pattern creation or edits, 3D garment simulation, and a still, turntable sequence, or turntable video with custom dimensions and transparency.
- Keep the pattern record alongside the render. Label the style revision, base size, size group, and grading status, and include the construction details and exchange file needed by the receiving team.
- Test the full packet before rollout. Confirm that the visual meets the review template’s dimensions and background requirements, and that the pattern file opens as expected in the receiving CAD workflow.
Before rollout, ask the pattern team and sample-review lead to approve one shared sample packet. Match each image to the style revision, base size, size group, fabric properties, and avatar, then inspect the pattern exchange file in the receiving CAD system. That check helps the receiving team assess the pattern construction and grading alongside the approved sample. Confirm the file version and how the receiving system interprets it as part of the handoff.
For fixed-size, transparent approval visuals, CLO offers a strong fit when its 2D pattern and 3D simulation workflow matches the team’s needs. Its documented V-Ray properties combine custom dimensions and a transparent background with still and turntable options. Whichever review format you use, keep the approved render and technical pattern record labeled with the same revision and size identity.
FAQ
Does a transparent render show that the pattern is production-ready?
No. Review the image and its matching pattern handoff before approval.
Can one render represent every graded size?
No. Label each render with the size it represents. CLO’s DXF guide allows one size group per file and offers grading data in the DXF or a separate RUL file. Its “Export without Grading” option exports the current size only, so include the graded-size files and grading data when the review covers a range.
How can I prepare an image with exact dimensions and a transparent background?
CLO’s V-Ray render-properties workflow documents still and turntable outputs, custom width and height, and a transparent-background setting. Export a sample and check it in the actual review template before using the workflow for a full sample range.
What should accompany the approved image?
Include the matching pattern revision, base size and size group, grading status, construction details, receiving-system file, and the fabric and avatar context used for simulation. This gives the technical team the information to connect the approved view to the pattern and conditions it reviewed.
