Want to make this? These are water caustics, the little squiggly things at the bottom of a pool (light refracting through the surface of water)
Here’s how.
-
Get a caustic texture, it should be black & white
Here’s mine:
-
Make it transparent
In my case, I used photoshop, and put the blending mode to screen on the layer, then followed this tutorial → https://www.youtube.com/watch?v=IvgzAjt0flc
Here’s my final texture
-
Create beams in Studio
- Place 2 perpendicular beams on top of each other.
-
Change their textures to your transparent caustics one
-
Change the Width0 and Width1 to make the beams plane-like rather than a line (I changed the arrow texture so you can see how its wider)
-
Change speed, stretch, etc. settings as you like
- Your done!
Here’s my setup. (these settings go for both perpendicular beams
