i need a similar effect like the new tilemap editor.

this is a city builder. when placing a building, i want see the grid only around the building/mouse pos.
i tried with lights but cant realize affect only one layer or a single tilemap, it affects whole scene/layers

any ideas?

some like this.... where the orange rectangle is the building, id want see the rectangles(grid) only around the building with that nice blur effect if possible

The way I would go about it is to have an alpha mask that moves freely and a grid image that is mapped to 'global' coordinates so it doesn't move. So the solution is probably a custom shader.

    Megalomaniak thanks Mega, i was trying not to using a shader but i guess its the only way, i will check

      Well, it's not necessarily the only way but it's probably the more optimal/performant way.
