Water Reflections Onto Objects (Caustics?)
I'm trying to get water reflections onto a cave wall using a spot light with a gel. The big problem is the repeating tiles. Is there a way to more randomize this in the material room?
Also, if there is a procedural shader way of doing this that would be ok too. I've already tried the cellular and turbulence mode but with no success.
I'm using Firefly, PP11.
Someone recently had a similar problem that, as far as I remember, was solved.
I looked at the link you provided and took a little from there, I think, I experimented so much I lost track of how I got here. I also took a bit from this link here Rotate texture map, how to and came up with this mish mash of what, I don't know. I'm sure it's messy and redundant but it's close to what I wanted. Trust me, I didn't math anything here, it was all trial and error, lol.
This is inside a cave with a slight overhang with water below it. I was trying to get the caustics to not go too high because I don't think they would actually bounce to the roof of the cave.
And the nodes.
