Cell Flow Settings

This page lists the settings on the Cell Flow dungeon config and on the layout graph nodes that are specific to this builder. The path, item and key-lock properties that every flow builder shares are covered in the flow graph documentation

Dungeon Config

Select your dungeon actor and look at the config

Property	Default	Description
Cell Flow	none	The Cell Flow asset that holds the layout graph
Grid Size	(400, 400, 200)	The size of a single layout cell in world units. The Z value is the height of one floor level
Max Retries	50	How many times the builder retries the layout before giving up
Parameter Overrides	empty	Overrides node parameters by name at build time, so a single graph can drive several dungeons
Marker Config	none	The marker settings asset that maps paths to the markers they emit

Create Cells

These are shared by both the Create Cells (Grid) and Create Cells (Voronoi) nodes

Property	Default	Description
World Size	(30, 30)	The size of the play area in layout cells
Min Group Area	20	The smallest area a merged chunk is allowed to have
Cluster Blobbiness	0.5	Controls the shape of the merged chunks. 0.5 keeps the classic behaviour, higher values create rounder more compact chunks, lower values create longer stringier chunks. Ranges from 0 to 1

Create Cells (Grid)

Property	Default	Description
Min Cell Size	1	The smallest cell the grid partition may produce
Max Cell Size	6	The largest cell the grid partition may produce
Fit Iterations	20	How many attempts are made to fit cells into the play area. Raise it for a denser packing
Min Aspect Ratio	0.4	Cells narrower than this ratio are rejected
Max Aspect Ratio	1.5	Cells wider than this ratio are rejected

Create Cells (Voronoi)

Property	Default	Description
Num Points	100	The number of Voronoi sites scattered across the play area. More points means smaller cells
Num Relax Iterations	5	Lloyd relaxation passes. Higher values even out the cell sizes and make them more regular
Disable Boundary Cells	true	Drops the cells touching the outer boundary, which are unbounded and stretch off to the edges
Edge Connection Threshold	0.2	Two adjacent cells are only connected if their shared edge is at least this ratio in length. This avoids connections through a sliver of an edge. This is an advanced setting

Create Main Path / Create Path

Both path nodes carry these Cell Flow specific properties, on top of the path settings shared by all flow builders

Property	Default	Description
Ceiling Height Min	1	The smallest ceiling height a node on this path may use, in floor levels
Ceiling Height Max	4	The largest ceiling height a node on this path may use, in floor levels
Room Size Min	1	The smallest number of layout cells a node on this path may merge into a single larger room
Room Size Max	1	The largest number of layout cells a node on this path may merge into a single larger room. Each node rolls a size between the min and max and absorbs that many adjacent free cells

Common Setups

• Bigger halls on the main path: Set Room Size Min / Room Size Max to something like 2 and 4 on the Create Main Path node and leave the branch paths at 1. The main route then reads as a series of large halls linked by narrow side passages
• Compact chunks: Raise Cluster Blobbiness above 0.5. Lower it for long stringy chunks that feel more like winding tunnels
• Tighter cave cells: On the Voronoi node, raise Num Points and Num Relax Iterations together. More points shrink the cells and more relaxation keeps them evenly sized instead of a mix of slivers and blobs

Note

Keeping both Room Size values at 1 gives one layout cell per node, which is how graphs behaved before this setting existed. Existing graphs are unaffected
