Hi!
I rendered a wallpaper using dispersion & caustics in Corona 4!
Looks great! Well done.
I tried this a few weeks ago (using a similar set up as done by Frood here: [https://forum.corona-renderer.com/ Caustics playground! #msg147874](https://forum.corona-renderer.com/ Caustics playground! #msg147874))
However, I couldn’t get such a nice result… and yours is even better!
Would you mind sharing your workflow for this?
I’m posting one with materials. Also i’m posting 2 screenshots. I made a disk targetted light with directionality to 0.8 and then i put a card with a little slit in front of the prism to narrow down the light even further. I’m sending the scene file also
CAUSTICS TEST PRISM.max (1.27 MB)
Wow, well done. Thanks mate, appreciate it! 
Does this scene render better/faster with Corona 5’s improved caustics handling?
