I need world mapped (world coordinate) material to mark orbits. Best would be if it used no texture, but only circular gradient.
Problem is that distances from center to orbit may be quite high. Simple scaling makes that line of marker thicker further i move.
And i need same width circular line for any distance from center (the star).
Maybe some polar coordinates trick would work with line mask texture. But i am kind of lost here.
In worst case i dynamically spawn some meshes with dots, but material would be best.
I also had idea of simple morph target material that is just expanding (slice of) circle from minimal distance to max.
But then again this mesh with above material would be best solution.
