Here is the setup, HMC with Rubeium biolumiescent anemones. While operating the cam and lowering it just below the surface, for a split second there are these tendril structures that are visible. The graphics engine quickly blacks them out but for just a split sec you will catch sight of them. That grid pattern, I assume, is the mesh structure of the planet itself.
