Blender is a powerful and complex 3D modelling and rendering package. And In my UI/UX career, I have learned this 3D Software and in my early stage, I have learned the keys to achieving anything in 3D realism.

the process of 3D modelling and rendering (what Blender does)

some rudiments of 3D analytic geometry (axis and coordinates)

orthographic and perspective views of a 3D object

local coordinate systems and child objects

the fundamentals of Blender's user interface (hotkeys, windows, and menus)

how to view a 3D scene from different vantage points (in Blender)

Texture and Shader Settings using Nodes.

The real environment and texture surrounding us are very helpful it has unforgettable memories, All we need is inspiration and some photos and use that as Material. I deliver the complete object with all the Lighting settings and Geometry Settings to the developer team so they can easily develop the desired environment or objects.
