Textures are images, not 3D models.

Indeed, many often confuse the concepts of "texture" and "model" without understanding that a texture is called a "wrapper" for the model, which is stored in the game as a 2D image.

I didn't write it correctly, but in any case, I can't create my own textures yet, I hope.

Creating textures directly is not that difficult - the question is whether it will look good. The difficulty lies in creating a new 3D model (even if it is not created from scratch, but uses ready-made "parts").
