Rust AI, NPC and animal convars

Quick answer: these are the Rust server convars for AI, NPCs, scientists, turrets, wildlife and farm animals, with the value each starts at. Type a name and a value in the server console or RCON, or put that line in server.cfg to apply it at every start. This list comes straight from a Rust dedicated server (Rust build 26431843, read 2026-11-06), and it is refreshed after every Rust update.

A Saved variable is written to cfg/serverauto.cfg by server.writecfg and read back at the next start, before server.cfg. The common ones are on Rust server variables. The other groups: Server and gameplay variables, Antihack, network and RCON variables, World, event and vehicle variables.

ai

Variable	Default	Saved	What it does
`ai.accuratevisiondistance`	`True`		When enabled, vision distance checks use per-bone raycasts for accuracy; disable to use a single origin ray for performance
`ai.aimedatangle`	`10`		The angle under which the AI will think it’s being aimed at at by a player
`ai.animal_ignore_food`	`True`		If animal_ignore_food is true, animals will not sense food sources or interact with them (server optimization). (default: true)

`ai.critters_startle_distance`	`0.5`		How close can a player get before a critter gets startled and runs away
`ai.debug_seed`	`0`		Seeds every Gen2 NPC’s random numbers from this and the order it spawned in, so a run repeats. 0 seeds each one at random
`ai.debugmovedraw`	`True`	Yes	Whether ai.selectnpc and ai.movenpc draw their DDraw markers - turn it off to keep the view clean while commanding NPCs.
`ai.debugmovegait`	`run`	Yes	Gait ai.movenpc uses when called without one - set it to walk to keep commanded NPCs at walking speed. One of: sneak, walk, jog, run, sprint, fullsprint

rustnav

Variable	Default	What it does
`rustnav.addtilebudgetms`	`2`	Main-thread time budget per frame (ms) for adding built navmesh tiles to their navmesh. A base rebuild lands dozens of results in one frame and the rest waits for the next one. 0 or less adds every result that is ready, which is what shipped before the budget existed
`rustnav.bakestatsenabled`	`False`	Collect navmesh bake statistics (rustnav.bakestats to read them). Defaults on in the editor, off on servers; flip on live to diagnose bake issues, then reset with rustnav.bakestats true
`rustnav.collectbudgetms`	`1`	Main-thread time budget per frame (ms) for navmesh tile geometry collection. The full-map bake wall clock is roughly tiles / (budget-worth of tiles per frame) / fps, so raise this while baking to trade frame time for bake speed
`rustnav.detailsampledistmult`	`12`	Detail mesh sample distance as a multiple of cellSize (Recast default 6). Larger = cheaper detail mesh, coarser surface height. Applies to tiles built after the change
`rustnav.detailsamplemaxerrormult`	`1`	Detail mesh max sample error as a multiple of cellHeight (Recast default 1). Larger = cheaper detail mesh, more height error. Applies to tiles built after the change
`rustnav.doorreassertspertick`	`24`	How many doors re-assert their gate state per navmesh drain tick. A rebuilt tile bakes its apertures shut, so every open or npc-openable door over the rebuilt area has to write its state again, and a megabase queues hundreds of them at once. 0 or less applies the whole queue in one frame, which is what shipped before the budget existed
`rustnav.drawkbps`	`512`	Max KB per second of navmesh tiles streamed to each rustnav.draw viewer

`rustnav.maxshoredistance`	`100`	Metres of open water past which default navmesh tiles are dropped instead of baked. A tile only drops when every point in it is that far from land, so shores keep their navmesh and so do rivers and lakes, which are never that wide. Independent navmeshes (oilrigs, tropical islands, ghost ships) are never touched. 0 or less bakes the open sea like before. Applies to tiles queued after the change
`rustnav.numthreads`	`4`	Navmesh tile builder worker thread count. Applied when the builder is (re)created - at boot, or via rustnav.setnumthreads at runtime. ~half the cores is the sweet spot for full-map bakes
`rustnav.savecompression`	`True`	LZ4-compress navmesh saves (smaller .navmesh files, no extra save time)
`rustnav.savedelta`	`True`	Append only the tiles that changed to the navmesh file instead of rewriting all of it. The first save after a boot or a rebuild is always a full write, and a full write also happens once the appended part grows past rustnav.savedeltabudget
`rustnav.savedeltabudget`	`0.5`	How large the appended part of the navmesh file may grow, as a fraction of the full file, before the next save rewrites the whole thing. A save whose changed tiles are a larger share of the mesh than this rewrites it too. Bounds both file growth and boot load time. 0 or less removes the bound, to stop appending altogether use rustnav.savedelta false
`rustnav.savethreads`	`0`	Worker threads for navmesh save/load compression. 0 = auto
`rustnav.savewarnms`	`1000`	Log the navmesh save completion line as a warning past this many milliseconds. 0 or less never warns
