# HoloBuilder 0.1.2

Large schematic display fix.

I forgot to remove a block display limit that was left over from the test version, which could make large schematics look incomplete after loading.

Fixed

• Removed the leftover test display limit from hologram rendering.
• Visible blocks are now selected by render distance instead of by their order in the schematic file.
• Improved rendering performance for very large schematics by using a spatial block index and rendering the nearest visible blocks first.
• Fixed a client crash that could happen when rendering outlines for very large schematics.
• Export now fails with a clear message if the selection contains chunks that are not loaded client-side, instead of silently exporting those areas as air.

Changed

• New exports now use the player's position as the placement reference, so reloading them keeps the schematic offset relative to the player reference point.

Notes

• Export is still client-side only.
• On multiplayer, HoloBuilder can only export chunks that are loaded by the client.
• If the export reports unloaded chunks, move closer, increase render distance, or export a smaller area.

HoloBuilder 0.1.3

Hologram rendering optimization update.

Fixed

• Reduced lag spikes while a hologram is visible by caching world/schematic comparisons for a few ticks instead of recomputing them every rendered frame.
• The HoloBuilder render distance cap is now actually applied; high Minecraft render-distance settings no longer force holograms to scan and render too far away.
• Cached Minecraft block-state conversions and parsed expected block states to reduce per-frame allocations during hologram rendering.

Notes

• Hologram block status can now update with a very small delay after world changes, which is the tradeoff that keeps rendering smoother.
• The mod remains client-side only.
