Density values that are greater than 0.15 are now more opaque, and the
transition between areas of total transparency (Opacity 0), and areas where
the Density becomes more visible (Density 0.15) is less gradual.
Adding self shadowing to texture density
Give the clouds some depth by adding self shadowing. Self shadowing causes
the fluid to cast shadows on itself using a single internal directional light at
-1, -1, -1.
To add self shadowing to the texture density
1 In the Attribute Editor, under the fluidShape1 tab, open the Lighting
section.
2 Turn on Self Shadow.
The clouds now have some darker areas on them, giving them some
depth.
3 In the Display section, change Boundary Draw to None to hide the
container. This gives you a better idea of how the fluid will look before
you render it.
