Hello to all,
I am trying to make an animation on a very low level, simulating the
movement of sand dunes. I tried to make it this way:
plane {
y, 0
texture {
pigment {
bumps
color_map {
[0.00 Yellow*0.1 ]
[0.25 Yellow*0.3 ]
[0.55 Yellow ]
[1.00 Yellow*0.6 ]
} scale <0.5,1,1.5> }
normal { bumps 30 phase clock scale <0.5,1,1.5> }
finish{
diffuse 0.8
ambient 0.1
}
}
}
when replacing "bumps" with "gradient" or "marble" or other patterns, I can
see the effect I expected, but with bumps there is only an effect in the
background, near the horizon, and in the foreground happens nothing.
What am I making wrong?
TIA
Rm
