Apple Motion: Creating 2D wave texture

Hello!


I need to create a wave animation in Apple Motion for a 3D model material (a video material).


I’m trying to figure out how to create a wave that animates. It just needs to be all white or varying opacity and it needs to animate multiple little blob of foam.


Here’s a reference image:



Look at the white texture. I am trying to create something either with particles, generators and other ways of creating content inside Motion.


Should I just create everything in Bézier paths and manually update their keyframes?


I am on an urgent deadline, so I really need some help on this.


Thanks for the help!

MacBook, macOS 12.7

Update:


I have been looking at tutorials and I think I might have found something useful:

I think I might be able to combine this "liquid" effect with my cloud generator... or perhaps use the ink bleed stroke?


I have progress but if I cannot get an opacity gradient and more weight at the front and less at the bottom, I might have to restart.

I actually figured it out right after I sent that, sorry. This is for an iOS game. My issue is that I cannot get it to work outside of Final Cut, despite my alpha type being set to premultiplied. This is very odd and random, but I tested a random animation in an app called Calipeg for iPad and exported a circle (one frame) as HEVC with alpha (that was really the only configuration option) and it seemed like the outline was basically not there? Perhaps I was tricking myself but it looked like it wasn't there anymore. I am baffled by what is happening. Anything I could do perhaps in Compressor? This is just weird. It's the same file type.

Ok. So I figured out a little bit more information. It seems that the background color of my scene impacts the outline color of the animation. I guess I'll set it to white if all else fails. Super odd. Any final ideas on weirdness with edges and transparency to prevent this? The only thing I could guess is that the edge is the area where that happens because it's semi transparent? Transparent videos is not my area of expertise so I am certainly learning as I go.

If you know the color your clip is going to interact with, in Motion you can select the Project (layer), go into the Inspector > Properties and set the Background Color to the color it will interact with. Set the Background to Environment (which keeps the solid color as an Alpha on export).


To be honest, I don't know if this will work — I don't really have any reason to use this feature. I can see where the edges along the alpha edge influence the lighter colors in a test project. This looks like Motion's method of premultiplying by a color (not just white or black).
