Strongylocentrotus purpuratus

The visible exterior of the purple urchin (Strongylocentrotus purpuratus), with attention to silhouette, spines and fine surface structures.
An offline CPU render of an original procedural model. This is an exterior asset study, not a current gameplay capture or a complete biological simulation.
Local spine refinements and Unreal Engine integration, animation and level-of-detail validation remain. The runtime captures elsewhere on this site show an earlier model.
