Modules

Module Bounds

Start by creating a Snap Grid - Module Bounds asset. You will assign a size for your modules here and use it while designing the modules

Right click on the Content Browser and create the Snap Grid Flow Module Bounds asset

Double click the asset to open the editor

• Set the Chunk Size to something like (5000, 5000, 2000). The X and Y has to be the same if you want your modules to support rotation. In this case, we've provided 5000 for both

• Set the Door Offset Z to 500.

Door Offset Z determines how high the door is from the base of the module. It is a good idea to leave some gap, so you have space to create some pits or lower areas

You'll drop this asset on each of the module levels you design

Modules

Create a new Level file. We'll design a room module in this file

Open this map file and switch to Unlit Mode

Drag and Drop the Module Bounds Actor on to the scene

Reset the Transform of this actor

Design your module inside the level bounds.

Note how the ground mesh was aligned to a height where it matched the door indicators (blue lines). These blue lines were previously configured to be 500 units above the module's base (DoorOffsetZ)

Go ahead and design the rest of the room any way you like

In this simple example, we want to have doors on all the 4 sides. A gap of 400 wide / 500 high was left out at the door openings. Our door and wall assets will eventually be of this size to fill up the gap

Do this for all the four doors

Optionally, Drop in a few lights and switch to Lit mode

In the next section, we'll create a Connection and add it near the door openings
