Array and Loops

Hi,

A year ago I asked about the possibility of adding Arrays and solutions to loop through them in VEG. I think the answer was positive, I can see texture Arrays, but no regular vector3 arrays or something like this. It is not really important, because it always an option to pass the array of positions in a texture form.

But it is still needed to loop through this texture in VEG nodes. There is no custom HLSL code node, right? Or I can't find it.

Anyway, is looping possible inside VEG, or it is on a Roadmap?
