Running /posteffect add <target> minecraft:entity_outline reports success in chat, but the post
effect chain is immediately rejected by the render thread and never actually takes visual effect.
Log excerpt (client log, two separate reproductions on different player targets):
[CHAT] Applied post effect minecraft:entity_outline to <Player A>
...
[Render thread/WARN]: Requested post chain minecraft:entity_outline can not be used as a
post effect because it uses targets inaccessible to post effects: [minecraft:entity_outline]
[CHAT] Applied post effect minecraft:entity_outline to <Player B> (t+0ms)
Requested post chain minecraft:entity_outline can not be used as a post effect because it (t+50ms)
uses targets inaccessible to post effects: [minecraft:entity_outline]
In the second reproduction, the warning appears only ~50ms after the command is applied, with
no resource pack reload involved — so the chain fails on its very first load attempt, not only
on subsequent reloads. This means the vanilla minecraft:entity_outline post effect can never
actually be applied via /posteffect add, despite:
Being one of the five vanilla post effects the game itself advertises as available
(minecraft:blur, minecraft:creeper, minecraft:entity_outline, minecraft:invert,
minecraft:spider).The command itself reporting success in chat with no error shown to the player, which is
misleading.
The same rejection also affects any custom resource-pack post_effect JSON that declares an
input with "target": "minecraft:entity_outline" — i.e. this isn't specific to the vanilla
chain, it appears the minecraft:entity_outline render target itself is categorically excluded
from the set of targets accessible to any /posteffect-loaded chain.
Steps to Reproduce:
Join a world (survival or creative, any gamemode).
Run /posteffect add @s minecraft:entity_outline.
Observe: chat confirms the effect was applied, but no entity outline/glow post-processing
is ever rendered.Check the game log / render thread output — a warning is logged: "Requested post chain
minecraft:entity_outline can not be used as a post effect because it uses targets
inaccessible to post effects: [minecraft:entity_outline]".
Expected Result:
Either (a) minecraft:entity_outline should be loadable via /posteffect add since it's listed
as a vanilla post effect and the command reports success, or (b) if this target is
intentionally inaccessible to /posteffect-loaded chains, the command should reject it up
front with a clear error to the player instead of reporting silent success.
Actual Result:
The command reports success but the post chain is rejected internally and never renders;
the player receives no feedback that the effect isn't actually active.
