This is my rendition of a bottlenose dolphin, it has a bone structure but does not include any animations. Textures are 4K and PBR for a great look in any program.
for simplicity the model has one primary texture including an albedo, roughness, normal, and diffuse channel.
The model is created natively in Cinema 4D completely in quads.
Other formats and additional subdivision (higher or lower) available on request. Check out my other models if you like this one.
