Copy geo to points and vary scale in each direction

[bootshank]

Hello, first post here.

I'm trying to do something that seems simple but I just cannot figure it out.

I'd like to take a piece of geometry and copy it to points, and randomize scale in each direction to give it some variation.  I've tried using rand() a number of different ways, in a for-each loop, but any time I apply a random change to scale in X, Y and Z each copy ends up looking identical.

It's probably dead easy but I'm stuck!

Thanks in advance for any help.

Well I couldn't make it work in a for-loop, but I scrapped it and just used a point wrangle on the points coming in to the copytopoints with this:

v@scale = 1;
v@scale.x = rand(@elemnum);
v@scale.y = rand(@id);
v@scale.z = rand(@ptnum);

I guess the key is varying the random element between each component, rather than using the same one...

Yep, you got it  Although instead of using three separate attributes, you can use '@id+123', '@id+456', '@id+789' for the x, y and z random seeds (or any other values you see fit). The rand() function just uses the seed you give it to generate a value from 0 to 1.

For simple cases you can use an Attribute Randomize SOP.

Thanks for the tips!
