Pressing 1-5 on keyboard will also change paint mode

2. Power/Height: Sets the height of your heightmap.
3. Radius: Set the radius.

You can change radius by holding Ctrl and scrolling the mouse wheel.

There is 4 different layers of heightfields that lets you separate geometry and create something like bridges, beaches with sand running under water etc.

Please note that AI Roads are forced to be at LAYER 1 for the time being.

What to set

1. material: when active the texture will be paintet
2. rotation: when active the rotation of the texture will be applied
3. flags: when active the tile flags will be applied

Tile flags

Tile flags define how geometry of heightfield is generated:

1. Detached - tiles will not be sloped to surrounding tiles of non-detached
2. Add wall - adds a wall to the detached tiles important for sidewalks
3. Wall collision - adds wall collision to set tile. (Not needed for sidewalks)
4. No collide - this tiles has no collision at all.
5. Flip UVs - Flip the texture uv.

Pressing Q-T on keyboard will also toggle the flags

TIP: Use "View Heightfield Tile-Helpers" in the View tab to show you what kind of tiles are painted on region. Each color represents a specific flag.
