Protoreaster nodosus — rigged 3D animal asset. Realistic adult horned sea star for normal game-view tropical shallow-water and aquarium substrate scenes, adding an original echinoderm body plan and reusable radial-animal authoring tools to the local library. Included formats: BLEND, FBX, GLB. The package includes the documented editable source and export files. Read the included README for scale, animation selection, import settings, LODs and known limitations. Only the documented checks were performed; independent review is not certification for untested game engines. Source lineage is documented. Commercial project use and modification are permitted under the applicable asset license; standalone asset redistribution is not permitted. Support covers missing files and reproducible documented defects, not custom modeling work.
