# AI Spawner placement
#### Legacy Documentation — Calysto World 5.7 and Earlier
This workflow is not the current Calysto World 5.8 workflow.
One of the popular requests I had was the ability to add enemies per biome. Creating a full AI spawner system would have been out of scope for Massive World but I have added the spawning logic on a separate graph so you can use Massive World to do the placement and make it spawn your own spawner system.
Look for the PCG\_BiomeWithAISpawner graph and duplicate it. It is meant to be added to your copy of the DT\_Biome (your biome database). The content of that graph is mostly the same as the PCG\_Biome with only the added spawners.
The added portion of the graph looks like this and I have added a few notes in it. The first one allows you to control the density of points where the spawner will appear, while the Density Filter will randomly remove a few ones.
Finally, your AI Spawner goes into the "Spawn Actor" node.
You can also hit "D" on the "Density Filter" node, this will put the filter on debug mode and show you an example of where the spawner will appear.
The debug will look like those small cubes from black to white.
