How to transfer vertex "uv" to point "uv" ?


Recommended Posts

Thanks all.

@Vig : Thank you. I actually was trying to use "attribpromote SOP". But as you can see this post attached the file, that was result.^^

@ Tomas : Thanks a lot always. Good tip.

I want to more talk to its issue.

that's exactly what I was talking about

since each point can store just one UV position it doesn't allow for split polygon islands

that's why you can have vertex UVs since each point contain one vertex per each neighbour face

why do you want to promote it to point?

note, that in max the UVs were vertex attribute as well

Hi, Luke.

You are right. I have a animated character and want to make breaking that with "voronoisFracture SOP". But I have a problem that it makes not sticky break mesh each frame. That is why I ask it question.

For more talk about it, I will prepare the hip file.

I hardly catch a cold so get some rest. Please keep my topic. Have a nice weekend.

Thanks again.

Hello again.

To talk more this post, I have prepared a hip file.

The hip file has including the reason I want to transfer vertex uv to point uv.

There is a character. I want to break with voronoiFractureSOP.

But I have got a issue in voronoiFractureSOP.

Each frame, It has a different result.

What is this solution in order to befix fractured object?

UVs will not help you in this case, neither area attribute or any other trick to get consistent pointcloud from scatter sop

since even consistent pointcloud will fracture mesh slightly differently in each pose

but you can do one very simple thing

store animated positions as an attribute on a static geometry

fracture that static geometry (that attribute will be interpolated to pieces)

use that attribute as point positions to get it back to life

here is the example

Tomas!

That's pretty amazing. Thanks all. Fabulous idea.

I wonder how you've got the its idea. Cool~

But I've a simple question.

As you can see attached image, no shared normal.

I have no idea about this solution.
