Underwater sunlight (NOT the Tangeringe Dream one :O)

Support Basics & Interface

HI,

I am looking for a tutorial or hint, how I can achieve the
effect of underwater sunlight beams “dancing” (I want to make a still, though) in the water.

I tried a plane ABOVE the scene, which I made
transparent with a high IOR…but it looks awful, because
its size is limited and the effect was not correct…

Any ideas ?

Keep blendering!

i would use an animated texture for the light instead of “real shadows” this way the hole thing is a lot faster and probably better looking. You could use the same texture for the halo…

you can use textures for halos??? how???

There is a tutorial by Enrico Valenza called “Bongo’s Environment”. You’ll find it here:

It might be what you’re after.

he uses a TUBE for the halos, which in my opinion look awful. And with the latest version of blender it’s possible to use a spot with halo (and everything else turned off) instead. The only interesting thing would be, if you can use a texture for this halo as well (at the moment it only works for the light, that hits an object).

Hi

I did this a while back now, but if you follow the link in my signature, I did some caustics and light shafts tests.

Hope it helps :slight_smile:
