Physical light simulation
Marciortiz:
Hi all,
I am not sure if I'm asking the question correctly, but how can we simulate an actual 3D physical light inside Corona?
I have attached some samples to explain a bit of what I am trying to achieve.
Corona has a very good way to deal with lights that I am trying to in fact create a light source that actually bounces and produce those rays of light that we got on real life, instead of using planes/spheres etc.
I saw a very good examples on past from Fryrender (Arion today) and I am just wondering if I can get some instructions for that?
Cheers for now :)

You probably mean caustics. :)
It does work by default in Corona but to make it render faster, just place a glass object in your scene, add a light and switch renderer from "progressive" to bidir or vcm.
Marciortiz:
Hi Maru, thanks for your reply.
So, if I for instance got a light bulb model and my inside fillet has emission material, would that work instantly?
Doesn't seem to work like that to be honest, as I did that test even with other shapes but didn't work.
I don't really mind about render time at this stage, I just want to get the most closed to light simulation Corona can deliver. :)
Marciortiz:
I just did a test with a light sphere also. didn't work either.
Not sure what to do :(

Did you switch renderer from progressive to bidir/vcm?
