Compatibility target: 6.45.1 The Swarm. Checked 2026-09-05.
No runtime game testing has been performed. Color seeds export to the game;
the preview uses original texture colors rather than an RGB tint. Game animation clips and skeletons were extracted and converted on 2026-09-11 using MBINCompiler 7.01.0-pre1 and a conversion-only NMSDK adapter. Original diffuse and surface-mask textures are shown with neutral studio lighting. Preview palettes use original game colors with an approximate seed arrangement. Prismatic surfaces and translucent membranes approximate game effects; exact seed palettes, biome lighting and bone variation are not emulated. Legacy fish C-F contain plain, unrigged geometry. Special fauna can have companion limitations.

Appearance and Arena update checked 2026-09-13. Fract cube uses an approximate red-orb effect reconstruction on the native creature animation socket. Arena field mappings follow NMSE CompanionPanel and round-trip tests.

Multi-region preview uses original procedural BASE, TINT, UNDERBELLY and fixed SKIN texture definitions and alpha masks. Palette selection remains approximate.

Geno-Prawn appearance preset: installed REWARDTABLE.MBIN / R_PB_MEDAL_EGG5. Names checked against game English localization. Featured diffuse and normal detail comes from original game textures, decoded using NMSDK channel conventions. ProtoDigger offers eight preview forms; preview choice is not an exported ground-form override.
