… i’ve worked on a while back. Textures for the floor were actually taken from photo references in a far too complicated workflow. I’ve shot the piece of parquet several times from a very near distance and then composed the whole one back together in gimp. Then i masked out bumpy parts of it by hand and layered a b/w version of it on top. Something like that. All in all they’re all separate objects and 3 pieces share one 8k (!!!!!!) texture each. It took about 2 1/2h to render with Photon Mapping and Final Gathering (inderectdiffuse shadeop).
All rendered with 3delight and exported from blender with my self-written renderman exporter.
And the chair is just a very simple object with a self-made renderman shader.
