Couldnt find any decent 3D cachalot so I made one and I can say its the best one out there.
Important: 1.Flippers are not modeled separately but flat against the body and cannot be 'T-posed' 2.Preview images were rendered in Marmoset and Sketchfab, there's NO ready-to-render scene in the Blender file.
Product includes: Original .blend file. I recommend you to export to your filetype of preference using this .blend .fbx and .obj files. .zip with all the textures (Normalmap, AO, roughness, height and 3 albedo maps: one normal color, one much darker, and a white, Moby D version).
