Map - cep - tion (n.) When a forged map can be divided up into sub-maps
Origin: from the movie Inception, a word explained to be "a dream within a dream".
Therefore, replacing the first syllable with a noun leads to "a {noun} within a {noun}".
As a little hook, I started inquiring about mapception when making a BTB map (Right now it's called Excavation, potentially in my Fileshare). My primary focus was to make an Infinity Slayer map with a side of Dominion. The problem was that I could not find three cohesive areas to plant my bases. What I ended up doing was spawning structures along a relatively open part of my map that was intended to be used primarily as a vehicle path. Essentially, this created a new part to a pre-existing map, a "sub-map" if you will.Then it occurred to me - what are the other uses that mapception could be applied to? Its not really that new of a concept; in fact, Multiplayer maps have utilized this for quite a while. Taking this one step further, one could make a map tailored to multiple needs while not necessarily remaining true to the original layout of the map.
Here are the two ways in which mapception can be applied:
1. Gametype Labels. For example, if I wanted an object to appear in Slayer but not Dominion, I would have to select "SLAYER" and "NO_DOM". Once the correct labels are applied, different objects will appear in different gametypes, if so specified. Everything is all together under one roof.
The downside of this is that your budget (not necessarily light budget) will still be drained for the objects you place, regardless of the gametype you're editing in. If this is a concern, you may want to try...
2. Map Derivatives. You take a map in its current state and make it a template. Then, use that template to make another map more suited to your requirements. A good thing about this is that there isn't any tedious labeling to do, or budgets to worry about. I'd recommend doing this for something like a 2v2 variant of a 4v4, or basically something not involving gametype changes. If you're going to change the gametype, though, it might just be better to use the labels. People won't want to sift through tons of maps to find one compatible with what they want to play.
You can combine these two concepts to create mini-renditions of the same sub-maps (eg. 4v4 size with Flood, Extraction; 8v8 size with KOTH and Dominion, etc).
Alternatively, you can go about with RevRight's concept here. This is a method that achieves the same results meant by mapception.
