Hi all... I have been doing a lots of water drops lately... And the biggest issue I encountered was that I couldn't achieve my drops to be more brighter , to have more light inside them like here for example Image
Here you can see that background surface is blue color and drops are light blue... The only way i did something simillar is by puting a light directly on a drop from camera angle, but that is not a solution...

Image here for example you see tons of light on bottom of the drops... I can't get that with octane :(

Any ideas on how to achieve more light scattering inside of drops?

You can't get this effect without caustic

I'm using Path tracing... is this good enough? or do I need to go to PMC?

Specular mat, ior 1.333, roughness 0, reflection 1.0 default water mat... Did I forget something?
I'll try to post a few previews of what result I'm getting

Do you use fake_shadow option? if yes, that is the reason.

Oh and one more thing, do drops need to pierce surface they are on, or they need to be slightly above the surface?
