How often a tile gets rendered (in seconds).

renderinterval: 1

How many tiles on update queue before accelerate render interval

renderacceleratethreshold: 60

How often to render tiles when backlog is above renderacceleratethreshold

renderaccelerateinterval: 0.2

How many update tiles to work on at once (if not defined, default is 1/2 the number of cores)

tiles-rendered-at-once: 2

If true, use normal priority threads for rendering (versus low priority) - this can keep rendering

from starving on busy Windows boxes (Linux JVMs pretty much ignore thread priority), but may result

in more competition for CPU resources with other processes

usenormalthreadpriority: true

Save and restore pending tile renders - prevents their loss on server shutdown or /reload

saverestorepending: true

Save period for pending jobs (in seconds): periodic saving for crash recovery of jobs

save-pending-period: 900

Zoom-out tile update period - how often to scan for and process tile updates into zoom-out tiles (in seconds)

zoomoutperiod: 30

Control whether zoom out tiles are validated on startup (can be needed if zoomout processing is interrupted, but can be expensive on large maps)

initial-zoomout-validate: true

Default delay on processing of updated tiles, in seconds. This can reduce potentially expensive re-rendering

of frequently updated tiles (such as due to machines, pistons, quarries or other automation). Values can

also be set on individual worlds and individual maps.

tileupdatedelay: 30

Tile hashing is used to minimize tile file updates when no changes have occurred - set to false to disable

enabletilehash: true

Optional - hide ores: render as normal stone (so that they aren't revealed by maps)

#hideores: true

Optional - enabled BetterGrass style rendering of grass and snow block sides

#better-grass: true

Optional - enable smooth lighting by default on all maps supporting it (can be set per map as lighting option)

smooth-lighting: true

Optional - use world provider lighting table (good for custom worlds with custom lighting curves, like nether)

false=classic Dynmap lighting curve

use-brightness-table: true

Optional - render specific block names using the textures and models of another block name: can be used to hide/disguise specific

blocks (e.g. make ores look like stone, hide chests) or to provide simple support for rendering unsupported custom blocks

block-alias:

"minecraft:quartz_ore": "stone"

"diamond_ore": "coal_ore"

use-generated-textures: if true, use generated textures (same as client); false is static water/lava textures

correct-water-lighting: if true, use corrected water lighting (same as client); false is legacy water (darker)

transparent-leaves: if true, leaves are transparent (lighting-wise): false is needed for some Spout versions that break lighting on leaf blocks

use-generated-textures: true
correct-water-lighting: true
transparent-leaves: true

ctm-support: if true, Connected Texture Mod (CTM) in texture packs is enabled (default)

ctm-support: true

Period between tile renders for fullrender, in seconds (non-zero to pace fullrenders, lessen CPU load)

Maximum chunk loads per server tick (1/20th of a second) - reducing this below 90 will impact render performance, but also will reduce server thread load

maxchunkspertick: 200

Progress report interval for fullrender/radiusrender, in tiles. Must be 100 or greater

progressloginterval: 100

Parallel fullrender: if defined, number of concurrent threads used for fullrender or radiusrender

Note: setting this will result in much more intensive CPU use, some additional memory use. Caution should be used when

setting this to equal or exceed the number of physical cores on the system.

#parallelrendercnt: 4

Interval the browser should poll for updates.

updaterate: 2000

If nonzero, server will pause fullrender/radiusrender processing when 'fullrenderplayerlimit' or more users are logged in

Join/quit message format for web chat: set to "" to disable notice on web UI

joinmessage: "%playername% joined"
quitmessage: "%playername% quit"

spammessage: "You may only chat once every %interval% seconds."

format for messages from web: %playername% substitutes sender ID (typically IP), %message% includes text

Debug: dump blocks missing render data

dump-missing-blocks: false

Have dynmap migrate old chunks to the new format for the current MC version (specifically, for migrating pre-1.13 chunks to 1.13 or 1.14). This is needed

in order to render chunks on an upgraded server (due to various bugs/limitations in CB/spigot 1.13+). This setting is NOT suggested to be enabled full time,

but only long enough to do a fullrender of a migrated world - it should be turned back off once worlds are migrated). It is EXPERIMENTAL, so be sure to backup

your worlds before running with this setting enabled (set to true)

#migrate-chunks: true
