Spline scatter on surface

[romullus]

I would love to see spline scatter mode enhanced by the option to project instances on surface. The projection could be performed in spline's local Z direction (preferably), or in world selectable direction. I imagine UI for the feature could look something like in attached screenshot. Such feature would be very useful in many practical scenarios.

Isn't that what the new includes/excludes option achieves? (But in reverse? So scattered on a surface but including a spline on Z axis)

Edit: Ah, I guess you want them to be equally spaced, as we can do with spline scattering?

Yes exactly and also in spline mode instances can be oriented by spline direction, something that's not possible in 2D surface mode.
