Create Spawn Room

We're going to create a spawn room and place a marker there to spawn the PlayerStart actor

Create Module

Create a spawn room module like before and leave a few connection points open

In this example, we've created a 1x1x1 spawn room with a single connection point

Placeable Marker for SpawnPoint

Create Asset

We want the theme engine to spawn a PlayerStart actor in the spawn room. Create a placeable actor asset named PM_SpawnPoint

Open the editor and add a marker entry named SpawnPoint to the Marker Names list

Optionally specify a preview sprite for the spawn marker

Save and close the editor

Add to Spawn Module

Open the Spawn Room module map file and drop this placeable marker asset somewhere appropriate

Register Module

Open up the module database and add this spawn room module like below

Set the category name to SpawnRoom. We'll use this category name in the flow graph shortly, to force it to use our spawn room while building the main path

Rebuild the module database cache Build Module Cache

Save and close the module database

Update Flow Graph

Open up the flow graph and assign the module database in the editor settings as before

Select the Create Main Path node and inspect the properties

Add an entry to Start Node Category Override and set it to SpawnRoom.

This will make the flow editor choose the start room registered in the module database with the specified category. As of now, we have only one spawn room, feel free to register more modules with the same name to have it randomly pick one spawn room

Hit build in the flow editor and make sure it generates a flow graph correctly
