I have been working on this for a while but have now got far enough to show off the oceans rendering.

Video.
Pics.
The videos shows that the player can interact with the "WaterSphere" just like the waterblock.

It still needs a little work on the shader.
Right now the reflect part of the shader is disabled till I can smooth out some issues.
The main problem with it right now is I can't get it to reflect properly around the sphere.

This is based off the waterblock and I will likely release it as a resource as soon as I can get the reflect figured out.
Shaders are not my strong point.

I am using this spherical code as the bases for a multi cloud and atmosphere layer as well.
My goal is to be able to get a atmospheric scattering effect going.
