ZBrush | Atlantic Sea Nettle, white

Switching back to animalia instead of human anatomy, below is an Atlantic Sea Nettle, in white. Sea nettle jellyfish exist in a number of species, and even within atlantic sea nettles there seems to be a decent amount of color and tentatalce number, and size variation — everything seems to be more interesting than you think!

These are really lovely creatures though, at least visually (they do sting).

Below is a final render and an overview of the process!

Process overview:
(0. Do a fun quick ‘frond’ study)

1. Use dynamesh to establish the basic form. This was more interesting than a blob-like creature would suggest as there were internal layers and details beyond the outer ‘shell’.

2. Retopologize

3. Add oral arm detail — the spiral brush was huge for this.

4. Add tentacles with an insert mesh brush. Tried fibermesh first, but ultimately an insert brush gave more control.

4. Pose — after exploring a few different ways to do this in Blender (rigging, deformations, soft body/cloth deforming) I actually came back to good ol’ ZBrush, using a lot of large and generalized brush strokes. Layes were added to the tentacles and jellyfish body so later I can add or make different poses. Again, the spiral brush was used a lot here.
