Sci-Fi Door gameready model

In this work, I train the skill of modeling in the style of hard surface and strengthen the skill of modeling under the subdivision surface.
This model has gone through all the pipeline stages to create a game ready low poly model.
Additionally, in this work, I studied in detail how to build a mesh suitable for modeling under a subdivision surface. I also learned many new ways to fix errors when baking texture maps.
P.S. Thanks to Pavel Inozemtsev (https://www.artstation.com/artwork/e0x446) for the ability to explain complex things in a simple way.
