Texture Seam Checker
Measure the borders, then see the tile—not just one flattering preview.
Compare opposite texture edges, measure seam error, inspect a repeated 3×3 preview, and check each PBR map for tile continuity.
Drop one or more tileable maps
Inspect supported images and ZIP entries locally in your browser. PLAYTEX AI compares the maps as a set, labels measured checks separately from visual heuristics, and shows the evidence behind each finding.
- Left/right border error
- Top/bottom border error
- Corner continuity
- 3×3 repeated preview
- Cross-map seam comparison
Pricing: This focused check and its evidence are free. Complete Material Preflight and engine-ready repair packaging require Starter or higher.
How does a texture seam checker find visible edges?
The checker measures color and luminance differences between left/right and top/bottom border strips, then renders the texture repeatedly so directional lines and corner discontinuities are visible. It reports horizontal and vertical evidence separately because one axis can tile cleanly while the other does not.
How the check works
- Upload the source files. Choose the real material maps or a ZIP so dimensions, channels, filenames, and decoded pixel samples can be checked together.
- Review measured evidence. Open each finding to see the affected map, observed value, confidence, and proposed repair instead of a generic pass or fail.
- Export deliberately. Choose an engine target, keep or disable individual repairs, and download renamed maps plus an import-settings report.
Confidence matters: dimensions, alpha ranges, vector length, edge differences, and memory are measured directly. Map meaning, baked lighting, useful resolution, and normal orientation can need filenames, a target choice, or artist review.
Texture Seam Checker FAQ
Are uploaded textures sent to a server?
No. Supported images and ZIP entries are decoded, sampled, and repaired locally in the browser. Closing the page clears the working set unless you download an export.
Can a texture pass numerically and still show a seam?
Yes. Low-frequency lighting, directional features, or normal-map orientation can reveal repetition even when the outermost pixels match. The tiled preview complements the border score.
Does this check UV seams on a mesh?
This release checks texture tiling edges. Mesh UV-island seams and padding require the planned GLB/glTF upload workflow.
