Transparent liquid in parfume bottle with caustics

[eddi_fuhrmann]

Hello again...

I try to build a parfume bottle for a friend and he gave me this as a reference:

I did pretty much the same with an outer bottle, inner bottle and the material on the inside. they all have max. transmission values and different depth settings...i have two questions now...i know the lightning plays a big role and a caustic effect was used...i found this tutorial but i can´t set it up right...

second..do you have some advice for the smooth shadows?

i will keep trying but maybe you have some good advice...thank you!!

Did you enable caustics for the glass and liquid shaders?

You can also fake pin-sharp caustics here.

What advice do you need? Larger lights produce smoother shadows. Increase the light samples to 3 or 4 to reduce noise in the shadows.
