Subregions

Each region can optionally have the subregions field, which is a list of other regions, each with its own unique ident as well as other fields.

Note that the radius and position fields of each subregion is relative to the parent region.

{
    ident=98

    color=0x5555AA
    faction=98

    count=3
    position={0.70,0.80}
    radius=  {0.05,0.10}

    subregions={ -- Ensure that each subregion has a unique ident.
        {
            ident=980

            color=0x8888AA
            faction=98

            count=1
            position=0.70
            radius=  0.30
            -- Other fields here.
        }
        {
            ident=981

            color=0xAAAA55
            faction=98

            count=3
            position=0.2
            radius=  0.1
            -- Other fields here.
        }
        {
            ident=982

            color=0x333388
            faction=98

            count=3
            position={0.00,1.00}
            radius=  {0.20,0.30}
            -- Other fields here.
        }
    }
}

Subregions can even contain other subregions, creating a region tree.

-- Many fields excluded.
{
    ident=980
    faction=98

    subregions={
        {
            ident=981
            faction=98
        }
        {
            ident=982
            faction=98

            subregions={
                {
                    ident=983
                    faction=98
                }
                {
                    ident=984
                    faction=98
                }
            }
        }
    }
}

Example of a Unique Region

The Makai & Monolith Orbital Runeworks mod uses nested subregions well by imitating the shape of its rune blocks with regions of different shapes.

(Fields that do not affect region map appearance have been removed.)

{
-- Deep Blue Background:
	ident=2671
	color=0x1E142B
	faction=267
	count=4
	type=2
	position={0.9,1.0}
	radius=  {0.2,0.2}
	subregions = {
-- Inner Light Orange Splats:
        {
            ident=2672
            color=0xEE915B
            faction=267
            count=2
            type=1
            position={0.2,0.6}
            radius=  {0.2,0.3}
        }
        {
-- White Outer Rim:
            ident=2673
            color=0xFFFFFF
            faction=267
            count=40
            type=2
            position={1.0,1.0}
            radius=  {0.1,0.1}
        }
    }
