Arnold Caustics workflow

[MayaGuru]

Hi guys,

I have been trying to get the result of "caustics" but it seems after trying everything it fails to generate.

1. I took a bowl with little extruded and carved faces to extract caustics.

2.I disable the opaque also and applied aiStandard shader with transparency full and ior = 1.55

3.Emit caustics are also enable under Advanced.

kindly suggest or share a video link to use caustics.

Are you using lights or emissive objects?

Here is a tutorial.

Can you share settings and/or a simple scene?
