Refer to the Import and Use Model tutorial. We can first import the model into the editor. Generally, the model is already automatically bound to the material, and the user does not need to do anything; if you want to modify the material, we need to click the duplicate & remap
button to generate a copy of the material and then edit the material copy.
Switching shaders will not reset shader data. For example, if the base color is red, the base color will remain red even if the shader is switched.
For specific operations, see the Shader Tutorial.
