PassThrough

PassThrough ignores entity hitboxes during raytracing for items on a whitelist. Holding a whitelisted item and right-clicking acts as if the entities were not there, so a block placed behind a player or mob can be targeted. The whitelist can be edited in a screen that accepts registry names such as minecraft:web, numeric IDs such as 30, and bulk lists separated by commas or newlines, either typed or pasted from the clipboard through an Import button.

The mod is a client-side tool for Forge 1.8.9 and covers minigame and utility uses, such as building in cobweb-heavy arenas. It can be switched on and off, a Smart Attack option suspends passthrough while the player is attacking so combat works normally, and left-click still registers hits. Settings open through the OneConfig menu, and a chat command toggles the mode. Server owners who run a community server can ban players who break its rules, since the mod itself makes no server-side change.

Only the client needs the mod, and servers run without it. The code is open source under the MIT License, and the source is published alongside the release. Files exist for 1.8.9 only, and the latest build, 1.0.1, was released on 2026-01-16 after a first publication on 2026-01-01. The mod is Forge-only and does not support other loaders or versions.
