Compatibility

Compatibility — VoxelCore 1.0.0

VoxelCore provides a separate server distribution for each supported runtime family. Install one matching server JAR. A runtime family is a compatibility target, not a guarantee that each version within that family has been exercised on a live server.

Minecraft version family	1.0.0 asset	Specifically smoke-tested versions
1.12.x–1.13.x	VoxelCore-1.0.0-mc1.12-1.13.jar	1.12.2, 1.13.2
1.14–1.19.3	VoxelCore-1.0.0-mc1.14-1.19.3.jar	1.14.4
1.19.4–1.20.4	VoxelCore-1.0.0-mc1.19.4-1.20.4.jar	1.19.4
1.20.5–1.21.3	VoxelCore-1.0.0-mc1.20.5-1.21.3.jar	1.20.5
1.21.4	VoxelCore-1.0.0-mc1.21.4.jar	1.21.4
26.2	VoxelCore-1.0.0-mc26.2.jar	26.2
26.3	VoxelCore-1.0.0-mc26.3.jar	26.3

These eight smoke targets were documented in the release source README. The source distinguishes passing CI smoke coverage from comprehensive testing of every intermediate Minecraft version or real Bedrock client behaviour.

Resource-pack compiler targets

Target	Pack format in the source README
mc-1.12.2	3
mc-1.13.2	4
mc-1.14.4	4
mc-1.19.4	13
mc-1.20.5	32
mc-1.21.4	46
mc-26.2	88.0
mc-26.3	97.1

Some rendering features are version-limited. Minecraft 1.12.2 predates resource-pack bitmap fonts, so the modern font/UI glyph pipeline is unavailable there. Newer structured item model features depend on newer server versions. Bedrock item models, block-state mappings and GUI rendering have additional limitations; do not infer Java–Bedrock parity from a successful build.

Server platform and add-ons

VoxelCore detects Paper's capabilities automatically and has a Bukkit-compatible fallback on supported servers. This document does not certify Folia. VoxelFurniture has its own renderer/version limitations, and VoxelVehicles ships a distinct build targeting Minecraft 1.19.4–26.3; check each add-on's own compatibility guide before installing it.

Reporting compatibility issues

Please include Minecraft and server-software version, Java version, VoxelCore JAR name, whether you use Geyser/Bedrock, and relevant logs. Open reproducible public issues in the VoxelCore issue tracker.
