Transfer vertex order between combined objects

[trs_andre]

I'm working on a blendshape script, and for it to work, I need the two objects to have exactly the same vertex order.

However, each of these objects consists of multiple meshes combined (face, eyebrows, eyes, etc.), and when I try to transfer the vertex order with the Maya method (selecting three vertices on one object and the same three in the same order in the other object), the destination object gets all wrangled because the vertex order is not being properly transferred.

Is this an issue because each object has multiple meshes combined? Is there any way to solve this?

Thank you in advance for any help!!

Just to update this problem, I ended up separating all the meshes and reordering the vertices one mesh at a time.

Hi André,

I got the same problem. Did you separate both source and target meshes and reorder vertices one at a time and combine them?

I have one source mesh with multiple floating objects, and a bunch of target meshes with the same topology as the source one. So I'm trying to find a way to transfer the vertex order without separating them (there're a lot of meshes) or query the vertex ID by their uv coordinate because they have the same uv.

I'll appreciate if you have any updates or better idea to share. Thank you!
