Vivecraft Sable Compat

Makes Vivecraft VR work properly while you are
standing on a Sable sub-level — a moving,
physics-driven structure such as a ship or a train carriage.

Client-side only. It works on unmodified servers.

What it fixes

VR teleport drops you into the void. You aim at a spot on the moving structure,
teleport, and fall through empty space far away from it. Vivecraft aims with a block
raycast, so on a sub-level it picks a destination in the far-off region where Sable
actually stores the structure’s blocks — then writes that position to you directly.

VR melee hits nothing. Swinging at a mob standing next to you does nothing, and the
log fills with errors. Vivecraft’s swing search box is built from two different coordinate
frames at once, so it spans ~20 million blocks. Sable refuses any query that large and
returns no targets at all.

Both are the same underlying problem: Sable keeps a sub-level’s blocks somewhere far from
where it draws them, and Vivecraft’s VR code predates Sable and does not know that.

Requirements

• Minecraft 1.21.1 · NeoForge 21.1.228+
• Vivecraft (verified against 1.21.1-1.3.15-neoforge)
• Sable 2.0.5+

Neither is bundled — install them yourself. Sable’s PolyForm Shield licence does not
permit redistribution.

Reporting a problem

The mod logs its own diagnosis: whether each fix loaded, and for every teleport, the
destination Vivecraft chose versus the one actually used. Play, quit normally, and send
logs/latest.log — that one file is usually enough. See
TESTING.md.
