The project consists of 8,333,866 vertices, 16,487,032 triangular faces and 8,316,309 faces. Because this model is too complex, when the model is pre-rendered, it will use up 80% of the computer’s memory. The reason for this situation is that I did not replace complex objects such as bricks, floors and walls with PBR materials, which will Save more memory for UV map and subsequent steps.

In the course of the project, most of the challenges I faced were carried out under technical constraints. Under this challenge, I have a better understanding of many functions of Blender.
