### Re: [TDU.RAND] slowing it down!

You won't get a smooth rotations with this function.

You should use a Noise CHOP operator to create rotation values for each particle (rx, ry, rz), translate it in time so the values change smoothly, then merge it with particles CHOP (tx, ty, tz).

Here's an example for you:

### Re: CHOP Noise question

Hmmmm.

I'm not getting this problem - on my machine the noise correctly moves along the x-axis.

What's your Operating System and build?

Also, make sure that your timeline isn't paused - expressions still cook when the timeline is paused, but OPs don't update in the same way.

### Re: Randomizer

You might use the built in tdu.rand for this instead - it would avoid the neef ro importing random.

The noise CHOP can also produce random values, so you could also do something like this by using a noise CHOP followed by a shuffle CHOP.

### CHOP Noise question

Hello!
I need to get noise moves along x axis.
I open chop noise node and set Translate tx = absTime.frame.
Translate's counter increases by one per frame, but image of noise is static. It not moves. So I can't apply noise to another node.

### Cpp Chop Triggers onValueChange without changing

Hi there, for a simple example I took the sample Cpp Chop and changed timeslice to false. Than I gave it a noise chop as input and attached a Chop Execute. The noise has constant values, but the Chop Execute ...

### Re: Copy SOP with chop pattern

... is off in the 099 experimental. The trick is to use something like me.copyIndex as your stamp that can then be used to find a sample in your CHOP with an expression like: op('math_noise_seg_1c')['chan1'][fetchStamp('index', 0.0)]

### Copy SOP with chop pattern

... maybe someone here knows how to solve it :) I'm trying to use a pattern CHOP as an attribute for a radius of an object being copied on a line. I ... so I'm wondering if there is a way to give each point a value from the noise, to have all 5 noise values stamped into the radius of the circle? ...

thanks Matt for those stats. A default Noise CHOP (nothing connected), with Time Slice On, was always 0.04. When you set its Sample Rate parameter ...

### Re: Sopto problem

The issue you're seeing is related to the noise CHOP.

You've entered the expression:

Code: Select all
`op('sopto1').numSamples - 1`

In the Sample Rate parameter, this expression needs to go in the end parameter.
