Deathwatch Crab

Named after the deathwatch beetle, this gigantic crab dwells in the dark reaches of the abyssal ocean. It is known to knock on the shells of crustaceans and aquatic vehicles in its search for living food.

Modelled in ZBrush, unwrapped in Blender, textured in Substance Painter and rendered in Marmoset.
The rock base is a photogrammetry asset from Quixel.

Some texture artefacts can be spotted on the Marmoset version of the render, not really sure what has gone wrong here.
