That is wild. I like it!
Please take a close look at the third image. On the bottom right hand corner there is a dolphin jumping above the water, but there is also an orange artifact in the rendering matching the length of the dolphin. Looks like slightly orange color water or reflection.
This artifact also rendered in an animation of this scene.
Even though the dolphins are the same component only this particular one is associated with this artifact.
What do you think may be causing this accidental visual effect?
