Caustics not showing up in playmode

Hi all,

I´ve made some caustics on a directional light in my VR project, but when i build lighting they are gone. And when i make them reappear somehow by randomly tweaking some values, they still don´t show up in playmode.

Any suggestions on that?

Thanks in advance!


How are you applying them? what are they part of?
Without basic information no one can help you…

Thanks for your reply!
Yea you´re right…I´m sorry it, was late.
I´m applying them as a light function with a material inside of a directional light.
They are part of an underwater VR-scene i´m working on.

Problem still persisting - püsh
Thanks in advance!
