I've followed the standard tutorial on creating caustics with Corona, but they don't seem to render out at all (using 3 hotfix1 at the moment). We need these caustics as part of the main render, so switching to PPM just to render them (as other tutorials say) isn't a workable solution.

I've attached the test scene, but the attached render shows what result I am getting.

Any ideas?

1) Your light source is tiny, so it's extremely hard to sample
2) You are using an IES light - I checked that disabling it helps render caustics
3) Remember that increasing MSI in the Performance tab will increase caustics intensity
Other than that I can only recommend waiting for the daily build with new caustics included. :)

Never underestimate the power of a well placed level one spell.
