You can use the Plane method if you're clever about it. Depends on how you use your picking. Just from using 3D experience though, Less faces is usually the better option so I'd vote towards Line2D or Sprite.
As for zooming in and out, I've seen little effect on PNGs really unless you get really really really close to these models/images/etc. If you can make the texture repeatable, you could do it simply with one giant plane, and repeat the texture across it till you're satisfied, unless it needs to be more dynamic then that. You'd have a square map, with a hexagonal field. On May 3, 5:12 pm, CyberHawk <[email protected]> wrote: > Well, i don't what to use a PLANE as that means my grid has to be > square in shape.
