After remeshing the sculpture it was time to texture it. For realistic PBR texturing I love to use Quixel Mixer. Its a great software, full of fantastic materials, and quite powerfull tools eventhough it stills on beta. I combined natural materials such as roots and clay, to make that rotten skin, and used personalized brushes to add the infected blood. I used a couple of UDIM tiles for the whole character.
