Hi!
I understand nothing.
Or I am already tired?
I attach a scene.
Sky_sphere is declared, but background transparent.

The default background colour is black. You did not change it, so, it's
still black.
Your sky_sphere is all black:
"sky_sphere { pigment {rgb<0.000, 0.000, 0.000>}}"
It's thus impossible to see it at all. It's not transparent, just the
same colour as the default cackground.
In this case, it's beter to simply set a background colour:
background{rgb<0.2,0.001,0.001>} // Dark red
Try giving your sky_sphere another colour, or some pattern.
Try using just a plain background, again, using some other colour than
black.

No! No!
One scene, one settings sky_sphere.
Sky_sphere - no, if I add in scene object created by means of meshmaker.
If it delete and add mesh or other - sky_sphere appears.
I hundred times checked before to ask.
Scene is attached pre, load and check.

It's a bug in the meshmaker include file, which overrides the scene
language version to 3.5.
The meshmaker file was designed to use 3.5 syntax, so it uses a
"#version 3.5;" directive to ensure compatibility with future versions.
This is not uncommon for default include files, and no problem provided
they remember and restore the previously-set version, using a construct
like this:
#declare Foo_Inc_Temp = version;
#version 3.5;
...
#version Foo_Inc_Temp;
Meshmaker tries to do this, but gets the construct wrong, issuing the
"#version" statement /before/ backing up the currently set version:
#version 3.5;
#ifndef(makemesh_Inc_Temp)
#declare makemesh_Inc_Temp = version;
...
#version makemesh_Inc_Temp;
#end //ifndef
This should instead be:
#ifndef(makemesh_Inc_Temp)
#declare makemesh_Inc_Temp = version;
#version 3.5;
...
#version makemesh_Inc_Temp;
#end //ifndef
The behaviour of sky_sphere with Output_Alpha=1 was changed with version
3.7, but for the sake of backward compatibility this change is only
active when "#version 3.7" or higher is specified. The new behaviour
makes the sky_sphere behave equivalent to a sphere with emission-only
finish scaled to a very huge size, whereas previous versions would hide
a sky_sphere in such cases.
