Image-to-PBR benchmark: PLAYTEX AI vs GenPBR 2.7

Name: Image-to-PBR default-settings benchmark: PLAYTEX AI vs GenPBR 2.7
Creator: justhim
Published: 2026-09-03

This test does not establish that either product is better. It publishes the raw outputs from one three-crop, default-settings run. Border-pixel deltas and encoded metallic values are descriptive diagnostics, not texture-quality verdicts. The two timing sets are not comparable. Anonymous access and output-channel counts describe product scope, not output quality.

Tested by justhim on September 3, 2026. Versioned edition: 2026-09-03.

Three image-to-PBR benchmark crops with PLAYTEX AI and GenPBR normal-map outputs — Three controlled crops from one first-party phone photo. This limited sample is meant to be inspected, repeated, and extended.

Results at a glance

Measured values and the conclusions they support
Question	PLAYTEX AI	GenPBR 2.7	Supported interpretation
Anonymous 512px generation	Free plan can generate/preview, but repository entitlement contract disables download.	$0 public generator, no account used; free-output license is non-commercial with attribution.	Access-policy difference only; not texture quality
Shared-map opposing-border pixel delta	17.172%	14.560%	Descriptive statistic; no seam-quality or product verdict
Mean encoded metallic value on wood	19.712%	35.342%	Descriptive statistic; no calibrated accuracy verdict
Observed processing timer	504.127 ms median, core only	466 ms median, browser result update	Not comparable; no faster-product conclusion
Output channels at tested defaults	7: albedo, normal, metallic, emission, roughness, height, AO	5 derived maps: normal, metallic, roughness, height, AO	Output-scope difference; channel count is not map quality
Commercial entry listed on test date	$9/month Starter; up to 2048px PBR maps and engine packages in the repository entitlement contract.	$9.99/month Starter; commercial rights listed on official pricing page.	Not like-for-like; licenses and bundles differ

The table reports observations without ranking the products. A lower opposing-border delta can come from flatter output and does not prove a better tile. The processing timers use different boundaries and cannot be used to call either product faster.

Neutral wood crop

Lower-glare section used as the baseline wood case.

Descriptive opposing-border pixel delta by shared map; this is not a seam or quality score
Map	PLAYTEX AI	GenPBR
normal	23.737%	5.124%
metallic	6.042%	13.487%
roughness	4.946%	21.278%
height	18.378%	14.298%
ao	18.315%	7.227%

Wood metallic output: PLAYTEX AI mean 17.181% with 99.733% of pixels above 0.10; GenPBR mean 34.400% with 99.999% above 0.10.

Source-to-height luminance correlation: PLAYTEX AI 0.9999; GenPBR 0.8611. This describes carryover; it is not a correctness score.

Methodology

Crop three 512×512 PNG inputs from the same first-party 1080×1440 phone photo. Do not retouch the crops.
Run PLAYTEX AI reference build 2ae3dbaf971b21895a84697b5775fa0509cfedf5 with material class dielectric, preset wood, and the checked-in defaults.
Run the public GenPBR 2.7 anonymous generator in Canvas CPU mode with every visible control left at its default.
Save the unedited PNG outputs. Regenerate the neutral and glare normals and compare SHA-256 hashes.
Measure opposite-edge RGB delta, decoded normal length, metallic leakage for a dielectric subject, and source/height luminance correlation.

Failures and limitations

One phone photo and three crops cannot establish a universal product ranking.
No calibrated height, roughness, AO, or spectral ground truth was available.
The glare and dark-edge cases deliberately contain lighting and boundary contamination; neither product removes the source problem at this stage.
GenPBR and PLAYTEX AI expose different product surfaces. The timing values are not equivalent UX timings.
Default settings favor reproducibility, not hand-tuned best quality. Skilled users may improve either result.
Meshy, Polycam, Scenario, AITextured, Adobe Substance 3D Sampler, and Hyper3D were removed from the ranking because this run did not test them under the same contract. “Not tested” does not mean “worse.”
