If you make an object paintable and then try to paint on one that is not
paintable, no stroke occurs. If you don’t make any objects in your scene
paintable, your strokes are placed on the ground plane.
To paint on a 3D object
1 With the terrain surface selected, select Paint Effects > Make Paintable.
2 From the Visor, select the brush named kelp.mel.
3 Paint a short stroke onto your 3D terrain surface.
When you paint directly on a paintable object, Paint Effects creates a
curve on the surface along the stroke path and attaches the stroke and
new brush to it. If you move the plane, the paint stroke moves with it.
4 Paint a few more kelp strands throughout the scene as shown.
The kelp brush orients the tubes to point along the normal of the surface
you paint on. In the ocean, kelp grows towards the surface of the water
in a vertical manner. If you want your kelp to appear realistic, it should
point vertically upwards. If you paint the kelp on an angled part of the
surface, the kelp tube will not point in a vertical direction.
TIP If you want to change the scale of the Paint Effects stroke to obtain larger
plants or animals, press the b key and drag your stylus or mouse to the left
or right to make the global scale for the current brush smaller or larger.
If you want to change the width of the brush stroke, to paint a narrower
or wider tube path, for example, a wider swath of kelp plants, press the
shift and b key and drag to the left or right.
