Solar caves

Testing mental ray materials and caustics, well, i like this one alot. The result os not final, light effects that i want extaly looks like a pointed light strings.

In my roleplay games, solar crystals is(one of) the most powerful energy source for clockwork and other magical devices, provides tne energies of thousand suns, which collected by aeons. (generally, the MOST powerful sources is solar too, but kinda... refined ) )

This crystal is warm to touch, but can store any amounts of clean solar energies - and glow smootly in the farest caves of cosmic fileds, along unknown and forgotten suns.
