I started using the mirror prefix in the OBJ file for chrome surfaces (as advised by dear Keet, at the beginning of the desired chrome group, write g sweethome3d_window_mirror_...). It turns out perfectly. You can adjust the color in the model settings, for example nickel, or gold, or copper. But so far only the polished version. I have assigned a light gray color for the faucet, door handle and hygienic shower according to the necessary groups. It turns out to be pure glossy chrome. If the color is dark gray, it turns out to be nickel. I don't have a model of the bottom valve, so I just took a photo of the temple from an angle and pulled it over the top of the cylinder. Also great. The photo with highlights should be rotated depending on the position of the viewer, it turns out like a real model with reflections. And I also found that if the mirror sphere is flattened, then there are no normal reflections on the render, the entire surface is covered with black pixels. I thought it was from a small size, I increased it 10 times. But everything remained as before, with a defect. So it is difficult to widely use mirror spheres, it is better to replace them with something else.
this is what a mirror sphere looks like in place of the bottom valve in the sink
and here is the photo on the top of the cylinder. Not to be distinguished from a real traffic jam))
Jack looked in for a visit). I realized that the white outline appears depending on the size of the original photo. If it is initially small and then stretches to human height, then the contour will be thick, if the photo is for a small box size, then the contour will be completely invisible. We need to come up with something simple..
Towels are a photo on a transparent background, not a model. It is very convenient to select them - there are millions of different colors on the Internet.
