About Voxy SeedGen
From ModrinthVery fast seedmath based LOD generator for Voxy
Voxy SeedGen
Fills Voxy's LODs straight from the world seed — a full 2,048 chunk render distance in under a minute
_This is an addon for Voxy, so it requires it and doesn't replace it_
Statistics
_Measured on Minecraft 1.21.11, 28 threads, structures on_
- N-sized worldgen, 2,048 chunk radius (Voxy's maximum render distance): 13.2 million chunks in 40 seconds, about 330,000 chunks/s
NOTE: SeedGen is NOT affiliated with Voxy or its creators, it only produces LODs for it
Capabilities
- Terrain shape, biomes, surface blocks, trees, foliage, and structures, all worked out from the seed.
- N-sized worldgen writes every area at the detail Voxy actually draws it at, by the same rule Voxy's renderer uses, and writes it finer as the player approaches.
- Continuous generation starts on joining a world and keeps the radius filled
- Overworld, Nether and End.
- Explored Areas are saved as normal
- Compatible with ALL NOISE BASED TERRAIN GEN MODS and CUSTOM STRUCTURE MODS
Usage
Runs automatically. Otherwise, Video Settings > Voxy SeedGen, or:
/voxyseedgen fill [radius] [threads]/voxyseedgen stop/voxyseedgen status
Settings
- Generation distance: 16 to 4,096 chunks, 256 by default
- Extended distance: Allows rendering up to the world border. LODs beyond 2048 will have lower quality
- Continuous: on by default
- N-sized worldgen: on by default. Off writes block detail everywhere (slow and inefficient, but neccerary in certain modded scenarios)
- Threads: a little under half your CPU threads by default, leaving the rest to the game and to Voxy
- Structures: on by default
- Trees: trees, and the scattered decoration of the Nether and End
- Water features: kelp, ice sheets and icebergs
- Debug: progress and a summary in chat, off by default
Requirements
- Fabric Loader and Fabric API
- Voxy and Sodium
| Minecraft | Built for Voxy | |---|---| | 1.21.11 | 0.2.16-beta | | 26.1.2 | 0.2.18-beta | | 26.2 | 0.2.19-beta |
Limitations
- Singleplayer and LAN worlds you host only, since a multiplayer client doesn't know the server's seed
- Areas Voxy already has aren't redrawn, so changed settings only apply to new areas
- The Overworld underground is solid stone, without caves or ores
_All credit for Voxy of course goes to cortex, its developer_
- _Feel free to report bugs or suggest features_
- \*not every mod tested, unintended behavior may occur
