// THINGS TODO
|

// - COMPLETED -- Better gizmo for grass brush (like a circle with a little line in the middle sticking upwards)
|
||||
// - COMPLETED -- Remove grass instances using CTRL + SHIFT + LMB
|
||||
|
||||
// - Maybe some kind of auto coloring system? I've noticed that mostly all grass in GTA inherits it's color from the surface it's on.
|
||||
// - Grass area fill (generate grass on ydr based on colision materials?)
|
||||
|
||||
// As far as everything else goes, the brush works just fine. No issues so far besides the UpdateGraphics() method. (causes flicker sometimes)
