PCG: Get Attribute from Point Index?

I feel like I’m missing something obvious here. I’d like to use PCG attribute data to modify the static meshes I am spawning. Say, scaling them based on a sampling of the landscape layers. ‘Get Attribute from Point Index’ can get the data I want, but I can’t figure out how to actually get the index of the current point. Any help?
Thanks

I need get the indexed array from a PCG Points Grid.
Anyone can help with this?
I dont find any way to do that.
Regards.
