Hello Dr. Sassi.

My goal is to animate a wave along a spline. The wave’s tip I want to displace and bend somehow and it should have a white water shader or something similar. But this whitewater part is only at the tip when animating. The next part is normal blue water and then finally a layer of ice should build over the normal water making it freeze in its position.(and not move anymore, even when the water tip runs further and expands the wave, which is why I needed the fixed V stretching)

That is what I want to achieve.

Thank you so much for your help.

Hi visutainment,

I have split the thread, as there is not so much anymore in it that would connect to the initial question.

The previous thread was here (for everyone reading along)

The key would be to know how you would like to animate the wave, what information is available, and how could that influence the steps after it. Perhaps a reverse process is needed, to have the material driving the displacement from the start.

This series will not cover materials, and the water is always there from start to finish, however, perhaps you get some ideas.

Some brainstorming:
The Ice chunks are typically partially moved by the wave since waves work on fluids and not on solids. At the moment the water would freeze, this partial motion would stop. Would you mind to share your scene that far on it, or a storyboard. I can provide an upload link if you like to keep it private.
The part that I don’t get, the water freezes, but the wave-tip moves on, and all of that in an animation that is driven by a spline only? The little tip would have no real power anymore and fade while freezing as well. Would you mind to share a little bit more about your approach? There are so many pictures in my imagination how that could look like, I’m a little bit lost here.
The main question, the wave is a mesh and is projected to a spline. The animated wave would be small in the beginning and stretched on end, going by the previous question. Too many questions and I need more input.

Example:

The ice chunks are not included, as this whole set up is not designed to hold clones on the surface. To get only partially with each question an idea what is needed, leads often to a restart, from scratch. One point needs to be clear, is that now all, or is there something more?

All the best
