The main reasons for the differences between the rendered materials and the actual ones are as follows:

1. The rendering will be affected by the ambient light to a certain extent, which will cause the difference between the materials and the actual ones; when rendering, a standard-definition effect picture can be used to test the lights. If there is no problem with the lights, then render the effect picture.

2. See if the different rendering materials are caused by the inconsistency between the door panel style attributes and the material attributes (e.g., using solid wood materials for the plastic-absorbing door panel style).
