}
};

想问的是如何把上述代码加以改动使得每个小几何体都有不同的颜色？

这里有一个不同颜色的小正方体的代码
file -f -new;
string $polyObj[];
string $SG, $shader, $clr;
int $k = 0;
for ($i = 0; $i < 10; $i++)
{
for ($j = 0; $j < 10; $j++)
{
$polyObj = `polyCube`;
move -r ($i*2-9) 0 ($j*2-9);
$SG = "SG" + $k;
$shader = "shader" +$k;
$clr = $shader + ".color";
sets -name $SG -renderable true -empty;
shadingNode -name $shader -asShader lambert;
setAttr -type double3 $clr (rand(1)) (rand(1)) (rand(1));
surfaceShaderList -add $SG $shader;
sets -e -forceElement $SG $polyObj[0];
$k++;
}
};
效果是这样的
求教各位大神啦！
