These extict animals are part of the CGPortfolio Prehistoric Shark Texturing Mini-Challenge at CG-Society. The raw 3D models are from the great Idaho Virtualization Laboratory.
I have increased the grade of detail and textured them in ZBrush. For example I’ve added detailed eyes, a hood for the nautiloid, some micro teeth to the sharks whirl and for sure scratches, folds and surface details.
The final renderings are done with Octane Renderer.
The Nautiloid
The Helicoprion
I hope you like them.
