@otowa Your katana texture looks good, Thibault! So far this is the only project this month that I’m not recommending you make it battle damaged or noticeably aged. The katana just has a pristine aura around it to me. Generally I do think that pristine things in CG is a tall order to make look good and interesting, but you Katana is a rare exception.
That said I don’t really have any notes. The texture is simplistic but that matches the pristine perfect nature of a katana. Even still you add some tonal flare to the gold emblem on the tsuba. It’s an A from me for week 2 👍
As for the shading of the blade, it looks like a single color texture may not be enough to achieve the look of your reference. Because it appears to me that the blade is 2 sharply defined colors (black to chrome, as you have) but there’s at least 3 variations of reflection roughness. I didn’t cover this in the stream or the treasure chest course, but you can paint a specific texture for the roughness values.
