How to merge multiple 3D model textures into one?

Question

3D

There is a model, but it is divided into several mesh objects, each with its own texture.
For the program you are using, you need to feed one texture, so you need to
1) merge all the textures into one file
2) change the UV-unwrapping (i.e. merge and move according to the textures)
The number of polygons in general is quite large to do it manually. Mesh objects 6 pieces.
Are there any automated ways to do this, for example in blender or max (or other programs)?
It's a common question, but I didn't find anything intelligible. Almost everywhere, they either do not describe it clearly enough (there is no modeling experience), or they suggest doing it manually.

You need to search for lessons by the phrase "baking texture". For example, here is a video from 2013, but it seems to show the basics correctly.
