most of this jellyfish was sculpted in blenders dynatopo. i refined the sculpt in zbrush, decimated, and bring back to blender. set the scene, with particles and volume for the water. materials are all completely procedural, so no textures used. rendered in cycles in 4 hours on gpu... slight enhancement of the render in photoshop, using a selection of the renderpasses...
Wow!
A lot of work went into that!! Very impressive!
