tranform sop with rand function??

[wufan927]

i tried to use rand(@ptnum) and rand(@primnum) in tx of transform sop, but it simply doesn't work the way i expected, is there a expression to translate point's position based on point number in transform sop??

Use a point wrangle instead.

// rand(seed) produces an output between 0-1.
float min_X = -10;
float max_X = 10;
// remap random value to new range.
float new_x = fit01(rand(@ptnum),min_X,max_X);
@P.x = new_x;

Also...

// increase in x by point number.
float inc = 0.5;
@P.x = @ptnum * inc;
