The Alcyonacea, or soft corals, are an order of corals which do not produce calcium carbonate skeletons. Soft corals contain minute, spiny skeletal elements called sclerites, useful in species identification. Sclerites give these corals some degree of support and give their flesh a spiky, grainy texture that deters predators. In the past soft corals were thought to be unable to lay new foundations for future corals, but recent findings suggest that colonies of the leather-coral genus Sinularia are able to cement sclerites and consolidate them at their base into alcyonarian spiculite, thus making them reef builders.
This 3D Model is composed by simple 2D planes with a transparent material applied (with alpha channel / opacity channel ), in order to give the 'look' of a 3D object.
It is a very light mesh, extremely low poly, perfect for videogames and live 3D applications, as well as for extremely populated 3d animation underwater scenes.
You can use this very light mesh and make millions of copies and still keep your scene not too heavy.
The texture is customizable, you can change the color of the coral . Be sure always to use both 'diffuse map' and 'opacity map' together in your material.
