Merging function for blueprint actors using geometryscipt

Hello,

I am trying to develop a tool to help me doing certain tasks for my dev. Here, I have already created a function used to convert a dynamic mesh component into a static mesh.

Now I am trying to extend it with a new function to convert a group of dynamic meshes into a static mesh.

I think my problem is with my loop because when I am executing it, I get this result :

I dont know where my problem is, I am new to blueprint’s logic so if anyone has suggestion..
Thank you!
