SOLVED: Underwater caustics and Gobos Tweet

[Namtar]

Hi there!

I wish to know how i can make caustics on Octane plugin.

Also, i wish to know how can make gobos (for lighting effects or fake caustics)

EDIT:

I'm sorry, i find the answer 5 minutes before i post this. I describe what i did, maybe it could be helpful for someone:

1.-Put a spot light in the center of some cilinder.

2.-Use alpha channel to make your gobo

Enjoy!
