Scene rendering done using Blender 5.2LTS (Cycles render engine)
Some object details was worked on ZBrush by sculpt
Underwater crepuscular rays was making with a Principled Volume and a Plane object on the surface with a material simulating the caustics shape ones they hit the ground. About 7minutes for render an image
Some assets like sponges have a simple shader masking using RGB channels for optimization and randomization on color map tint. Was masked using Red(for Ambien Occlusion), Green(for Curvature details) and Blue(in some cases for Thickness masking or a hand painted mask) all done on Substance Painter from the higher mesh and used on Blender like this way.
