[Closed] How to create faces in an Edit_Mesh modifier?

Hey,
I’ve made pflow emitter, emitting triangles with their 3 verts at the same position.
I use a mesher coumpound to export this as alembic. Basically i’m just interested in those vertex positions, but the engine requires faces to support verts.

Now i’m trying to optimize this.
I added an edit_mesh above my mesher and weld each 3 verts with a little threshold.
So i basically have a vertex cloud with a uv coordinate for each vert, moving each frame.
Since there’s no faces, the edit_poly modifier erases the uv channel so i have to stick with edit_mesh.

I want to create an arbitrary mesh from this vertex cloud inside the edit_mesh. Something similiar to edit_poly createFace. Or any function that would create a face like i could manually do with the edit_mesh create face tool.
And well i basically can’t find it.

Thanks for your ideas.

I’m adopting a new strategy. Create an editable mesh with n vertices, arbitrary faces, animating verts position to match particles,.
