I’m trying to create an underwater scene where the lighting appears like you would expect to see underwater. An example is here:
where you can see the light hit both the objects as well as the floor. I don’t mind a repeated animation but I would really like to get the lighting effect to be fairly dynamic and give the impression the player is underwater. I suspect I need to have a transparent texture with some animated caustics which a light source must project through but I’m unsure how best to go about it.
Any pointers?
Edit: I’m not looking to show the water level on top like in the image.
It generates a really good caustic noise (as seen it the picture in your post) and the free version allows up to 12 frames of animation and it is always loop-able. Then you only have to place it on an atlas or something and have a script scroll trough it while it is a light cookie.
