3D MAX asked the master ... why can't my effect always come out? ...

Reflective objects such as glass and stainless steel are not only dependent on the adjustment of materials, but also related to the environment you reflect. Without good environment and lighting settings, they will also have good results. For example, you can make some self-luminous white films around you to simulate the feeling of lighting, and some reflected objects will look better. You can also make an HDRI with lighting setting effect in the studio.
