I am trying to replicate caustics from this video:
In the video it looks like the creator is using a noise map to generate displacement, thus generating caustics. I have everything set up correctly, caustics caster, solver and emmiter, however no caustics is being generated under displaced mesh.
However, if I displace the mesh using the displace modifier (using noise or musgrave texture), caustics does get generated under the mesh. It also generates if I use the ocean modifier.
So it seems like, for me, caustics works only if geometry is displaced through an actual modifier and not through a material output. How does it work for him though?
Would appreciate it if somebody tried to set up the scene like in the video.
Yes, that’s exactly how I set it up. But again it doesn’t generate caustics. It generates caustics only through the Displace modifier. So the geometry has to be actually displaced in the viewport.
I know what you mean, but it’s still displacement through a material output.
