Summary

Hello I would like to see if it's possible to do material acquisition (albedo, diffuse or basecolor, roughness, normals,..) on planar textures or objects based on a real photo sequence.
Object model would typically come from a photogrammetry software with uv.

Thank you for your work.

Hi @materialjan,

After following the various inverse rendering tutorials in the documentation, you should be able to implement a script that performs such optimization.

You can try optimizing the parameters of a textured principled BSDF combined with normal mapping.
