Exactly. Thanks, Dr. Sassi.
Such a great tool, which I have never used or thought of using, until now.
Enjoy your time off, and have a great 4th of July.

Never mind! Found the video; it was Chris Schmidt's (always excellent) roundup of new features from C4D 2024.4.
The tool is the "Property Transfer Manager" and it's buried in the "Character" tab. I never thought to look there.
In any event, it seems to do exactly what I need.

I'm positive I had watched a Maxon video, from one of your contributor experts, and they detailed how you can transfer a UV map from one object, to another similar one. But I can't find it now.
I need to do precisely this. I have the same object; one version is very-high poly, the other very low.
I unwrapped the UV's on the low one, because the results are very good. But I need to use that on the high-poly model, for final texturing.

How does one do this?

Thanks!

Yeah, absolutely. I see the inherent complexity in something like that. I'll be able to really test your solution on an actual work project this coming week. So I can report back, depending on what I wind up doing.

Have a great weekend!

Wow, cool. Thanks, Dr. Sassi. I'm studying the key aspects of what you built, so I can understand more of what the operations are. Initially, it does look like the operation is generating individual polygon edges > splines and that's what you used to drive the eventual sweep.
So it's not necessarily one single spline, but many. So I might not be able (for instance) navigate an object / light around those pieces with something like the align to spline function. But overall, this still seems like a very solid option for other effects.

Cheers!

Good morning!

I'm wondering whether there is any method, to generate a parametric spline from a boolean of solid objects?
I've attached the simplest of scenes, for example. In it the figure is being cut away by a cube. I would like to be able to generate a spline outline of that red region. I would then use that spline for other effects; generate particles, sweep with other geometry, etc.

Simple enough as a still...but not if the cube is animated.

Is there a function or series of functions, which can accomplish something like this?

Thanks

Thank you, very much, Dr. Sassi.
I'm studying your invention, and I'll see what I can gain from your generous investment of time.

Being that I still need to find a solution for a current job. Maybe I can pivot this a little. In my example scene, I need to change the shape of the splines & spline mask. One thing I need to do, is soften / chamfer the harder edges; but I need to maintain the parametric nature of the object.
As it stands, the only "chamfer" solution I know for splines, is destructive. I've tried throwing the "smooth" deformer at the splines, as well as the delta mush deformer; but neither seem to have any effect on splines - only polygon objects.

Any thoughts, Dr. Sassi?

Cheers!

Thanks, Dr. Sassi. I'll watch that video, in its entirety. Once I get through the job that required figuring something like this out...

Hey,

I'm dipping my toe (barely) into object node creation. I'm wondering what the steps might be, to recreate the parametric shape in my attached scene, as nodes. Right off the bat, I didn't see any obvious node for MoGraph; so not sure whether that is simply not available in that method of object creation? Is there another node / combination of nodes, which afford similar features as MoGraph?

Thanks, for any initial guidance.
