VoxelMap x SeedMapper by CevAPI

VoxelMap x SeedMapper is a heavily modified fork of VoxelMap Updated with SeedMapper integrated directly into the client.

This fork combines VoxelMap's minimap and fullscreen world map with SeedMapper locating, overlays, loot tools, persistence, UI integration, and a range of rendering and behavior fixes.

Notes

• This is not intended to be an upstream-equivalent release.
• Some legacy localization keys may still remain after UI changes or removals.
• The project prioritizes SeedMapper integration and UI consistency over strict upstream parity.
• Project is still undergoing and there may be some bugs.
