Hi Stav no problem, looks like you've got the hang of it already.

It might be easier to control for your case there if you would slice out the local section of the sphere you want to apply it to. That way you wouldn't need to make a lot of padding around the base plane.

You'd want the slices to be aligned with the control point UV grid of the sphere, the easiest way to do such a slice is to select the sphere, then run the Edit > Trim command and push the "Isocurve" button in the command options area. That will then let you pick UV lines on the sphere something like this:



You can use the Direction dropdown to set whether each pick makes a line of "latitude" or "longitude" on the sphere, or both. When you're done placing the cutting lines push Done or right-click in a viewport, then at the next prompt to select which pieces to discard switch the mode to "Mode = Keep" and select the region to keep, like this:



Then right-click to finish that step and you'll have a result like this:



Now if you use flow with this sphere fragmenet as the target surface your base plane will map to just that area so you can make the base plane to be tighter around your objects.
