Not great
I tried Chord.
- The metal texture isn't being generated. It's always black, no matter what input image I use. Not even with a very generic obviously metallic one.
- Likewise the roughness is borderline useless. It doesn't recognize materials at all.
- The basecolor texture becomes blurry. Doesn't matter what size you pick, it will always turn out blurry.
Overall Chord is worse than a generic normal map generator.
Hi,
Thanks for your interest in our work and for trying out our method. To answer your questions:
[1] & [2]: You are absolutely right. The metallic and roughness predictions from Chord are not always accurate at the moment. This is because the roughness and metallic estimation currently relies on a greedy search strategy to generate the initial image, meaning the initialization can significantly influence the final result.
[3]: You are also correct here. Chord is based on the SD2.1 architecture, which is limited to a resolution of 768×768, and SD2.1 itself is no longer the most advanced backbone available. As a result, Chord can sometimes produce blurry outputs due to both the resolution constraint and the limitations of the underlying architecture.
We are currently working on an improved version built on a more advanced model architecture, which should provide noticeably better detail quality and sharper results.
