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 maps you intend to tile. Check the source color texture or a coordinated material set so the report can compare both axes and show which maps contain an edge mismatch.
- Compare the score with the repeated preview. Look for a line at each tile boundary as well as repeated stains, lighting gradients, and directional features. A low edge error alone does not prove a natural-looking repeat.
- Repair the source, then recheck the set. Upload the existing source color texture to Seamless Texture Fixer for crop, alignment, and edge repair. Regenerate derived PBR maps from the approved source and check the final set together. Mesh UV seams and normal orientation require separate fixes.
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.
