# How to iterate through different objects with only one object info node in geometry nodes

I have an OBJ sequence exported from Houdini. I have imported the entire sequence into blender, with each object being one frame. I want to make a separate object with a geometry node tree that imports the correct object in the sequence for each frame, so that it iterates through the list as the frame number increases. I could do this with an object info node for each one, and a lot of switch nodes, but that would take forever to set up and could not be used on other sequences. I am aware of the stop motion OBJ addon; the reason I am doing it this way is so I can copy the vertex positions onto the geometry of the first frame so that it is no longer a sequence but an animated mesh ( I think that is how it works?)

You can put them all in collections, and use a Collection Info instead. The exact method would depend on your project, but you can instantiate, delete or otherwise manipulate them after that, by matching their indices with Scene TimeFrame. Here are two example setups:
