I’m making the Infinite IKEA (SCP-3008, look it up, it’s pretty cool), except that’s it’s a square kilometer in area (1000 blocks by 1000 blocks) instead of being infinite. Now, in the IKEA, the day/night cycle is simulated through the lights shutting on and off. Considering my ceiling (and the cannon ceiling, probably) is at build height, using lanterns is a no-go. Therefore, I have opted for command blocks that simply alternate between a glass and iron ceiling. I say blocks plural, because each command block manages a sector of a hundred square meters. When one activates, a chain command block activated the next module, and so on.
Now here is the problem. If the command block is manipulating blocks that are out of view, you will get an error message saying that “blocks outside the world cannot be accessed”. Therefore, I need a way to load every chunk at once. Ticking areas will not work, as they cover at most sixteen hundred square meters, and you only have 10. I’ve tried altering my render distance through the game files, but to no avail. Is there a program that can either increase the ticking area’s power or force load many thousands of blocks? (A bit over a million).
Preferably, I would want this solution to be accessible to mobile, but if this is not possible, then that is fine.

While in the shower thinking about how to best implement a function, I stumbled across a possible solution for your problem: have many smaller command block chains that command a couple chunks around them. You could probably testfor a player and then set the blocks accordingly. The SCP you referenced will likely not have super large rooms, so you'd probably be able to get away with this system.
I'm going to keep my other answer up, because other Googlers will end up here, and because it will work in the future, but for now we're stuck with Vanilla mechanics.
