ModernSpace v0.1.0 — Initial Release

ModernSpace is a dedicated Forge 1.20.1 port and modern remaster of PersonalSpace from GregTech: New Horizons. It allows players to craft a portal, design their own private pocket dimension (custom block layers, biomes, sky colors, daylight cycle, streets and building lots) and step into an isolated, lag-free realm.

🌟 Key Features

🌀 Personal Space Portal & Seamless Teleportation

• Altar Gateway: Craft and place the Personal Space Portal (obsidian altar with a swirling Nether Portal pool and floating enchanted spellbook).
• One-Block Creation: Placing an unlinked portal immediately opens the in-game World Editor GUI.
• Portable Link Memory: Breaking an active portal preserves its dimensional link inside the dropped item, allowing players to relocate their portals anywhere without losing access to their pocket realm.
• Automatic Return Portal: Finalizing your settings generates the runtime dimension and automatically spawns and links the return portal.

🎨 Interactive In-Game World Editor GUI

• Multi-Layer Terrain Builder: Configure dimension floor layers block-by-block (Bedrock, Stone, Dirt, Grass, or any modded block) with customizable layer heights, search bar, and presets.
• Legacy String & Registry Converter: Full compatibility with classic GTNH preset strings and legacy modid:name:meta identifiers, automatically converting them to modern Minecraft resource locations and tags.
• Atmosphere & Visual Controls:
  • Customizable sky color via RGB picker.
  • Toggles for clouds, stars, and weather states.
  • Daylight cycle configuration: normal 24h cycle, eternal daytime, or eternal night.
• Biome & Vegetation Control: Pick any registered biome and toggle natural tree and flora generation.
• Generation Lock Protection: Terrain generation is locked upon first use to safeguard against chunk corruption. Server operators can grant one redesign via /pspace allow-worldgen-change. Visual settings (sky, clouds) can be re-tuned at any time.

📐 Urban Planning: Streets & Lots Grid

• Divide your flat dimension into an organized urban grid of building plots (lots) separated by roads.
• Configurable street widths, lot sizes, and custom road/border blocks (concrete, stone, asphalt, etc.).
• Optional center marker block to easily locate the spawn origin.

⚡ Tech Mod & GregTech CEu Modern Integration

• Solar Power Compatibility (gtceuSolarPanels): GregTech CEu Modern solar panels, solar covers, and solar boilers detect sunlight and produce energy within personal space dimensions (enabled by default).
• Wildcard Block Rules: Server configs support path globs (e.g. gtceu:*_casing, antiblocksrechiseled:*, #forge:stone).
• Safe Full-Cube Validation: Wildcard block rules automatically validate that only solid, full-cube blocks are accepted, preventing client rendering glitches and server crashes.
• Out-of-the-Box Mod Support: Pre-configured support for GTCEu decorative blocks, GTCEu lamps, GTO ABS casings, and AntiBlocks Rechiseled.

⌨️ Full Administration & Command Suite (/pspace)
