Alembic fracture

[feresteanud]

Hello,

Maybe some of you had already this issue that I have at the moment and really appreciate the help. Trying to figure it out for almost two days and still no result. The problem is like this: 

- import the alembic from maya

- convert it to polygons

- then make a selection and delete what is not selected

- when I play each frame I have another set of polygons like in the image attached (I cannot upload the file). Hope some of you have some ideas. 

Thank you very much

might be that the alembic has changing topology aka polycount

What is actually changing is the point numbers but only when I apply voronoi fracture node. The alembic file is just like a grid and the point number doesn't change at all. It stays as in the first frame. Point numbers start to change when I apply voronoi node. The solution for this (just tried right now) is to export it as fbx file and everything works fine. But just wondering why alembic behaving like this, maybe there are some situations when you cannot export the file as fbx.

is the geometry animated? if yes it probably is the reason for changing point numbers after voronoi. there are a couple threads here dealing with fracturing animated objects in a way that the voronoi stays the same.

if thats not the case it's hard to debug without a (example) scene file

It is an animated geometry. So this is the reason. Ok, thanks. I'll have a look to see if I find some threads. Thanks.
