I’ve tried to make things with lots of reflectances to look realistic, but they don’t really look like this. How do people do this, and how is there so much reflection?
You can add reflectance up to around 400 and down to around -400, so there’s a lot to work with. Usually if you want a realistic reflectance, I wouldn’t use more than 2.
Just for a cool effect, you can experiment with negative reflectance and really high reflectance.
