Abstract aquarium

As it appears to be a trend, a small WIP diorama ([Nice one here!](https://skfb.ly/6xvV6)) just to try out some lighting technique for an incoming model (not a WIP I hope). The refractive "box" around the model is just eye-candy, what was really of interest to me was to get an idea about bubbles (spheres with an emissive material coupled with dithering transparency), sun rays (elongated planes with blending opacity and a light emission to them) and the ground lights (not done well here, but basically voronoi textures to simulate the effect of waves on the light, baked on the ground model). The ground is a quick and ugly dyntopo sculpt done in blender, while the little fish are just a particle system set with a lowpoly mesh as render object. A nice point to spend time on will be the ocean surface, to do with the appropriate modifier in blender, and a refractive/small-scale-roughness/foamy-at-the-edges material. Plus, I should try to animate rays, bubbles and fish (as boids) to give it a living touch.
