Hi guys. I’m looking for pointers on how to do the following 3 things:
- Display/project an overlay on top of a hex tile (mesh).
- Ability to toggle this overlay on and off.
- Ability to customize it (mainly color and opacity)
I read about Decal and it sounds like something that would work but I didnt entirely get the result that I want. The geometry of decal is always a cube and Im not sure if I can change it to another shape that would match with the target face of my mesh: a hexagon. From what I see if the decal is bigger than the target face then it would also project onto faces perpendicular to the target face.
Also some background of my end goal: I want to recreate this scene from a childhood game, basically a turn based rpg.
When a character is clicked, the game shows an overlay on top of tiles the character can move to. I figure this is 2D so the developer might have just built the grid separately, layered it on top of the background and toggle the overlay on or off.
