All of the default segments was created as a whole room segment.
All floors and ceiling that i use are created by my self, so i have many varyations
And so i then have walls made as their own type, and also with the floors, and so i can then swap and change floors or walls without to much of a hassle of one effecting another.
But i know what you mean and it is rather a pain.
Just to mention is that one bit of software to make such contents is called Firmsa v2
it will allow you to create the ceiling and florr as wella as the inner and outer walls.
If i remember correctly to paint floor you then select floor and also select the interior mode also, and again floor mode with external mode to paint just the ceiling.
i will go and have a try as i have not tried it out yet as i make all of my own.
Edit:
Well i did go and have a proper try, and as mentioend.
changing just the floor in a room that is made from another room segment also changes the room/wall or floor to the one that the wall or floor is from, eithe if you just select the paint only wall or floor. also tried Lower Mid and Top of the same room segment in turn on there own, and they also change other parts of existing room.
Note: all room segments was tested from the Ww2 Chateau and bunker Storage Area.
So in short , part of a segment can't completly work on its own when using in an area where there is already another type of segment, so part of the segment don't work independantly, and thus this is an editor issue and not of a room segment.
But if the floor/ceiling is made sepratly and also the wall, then either one can be changed for another one with no problem.
It just seems to be if a segment is created with the walls and floor/ceiling all in one that they can't be painted properly as a independant item into another room segment.
And the only option/solution is the way i do mine all the time, and that is make the floors and walls seperatly.
Using such a software like firma will make your floors & wall in no time at all.
