Re: How do I find out the maximum and minimum values (y)?

Very true Eric, thanks for that. However, with the Analize CHOP, I noticed that if I want to get the maximum/minimum value of an LFO for example, or a noise CHOP set to Time slice, I need to hook up my CHOP to something like a Trail Chop first, ...

Re: Different rotation for each particles instancing

you're close, you need to play with the noise more. The number of channels in your noise chop are way more then in your particle system. You should change the length of the noise chop to reflect ...

Different rotation for each particles instancing

Hi guys, I made a particle system and I tried with a noise to rotate each particles individually. I followed some examples on different ... at the moment turn in the same direction and i don't know why. I use a Noise CHOP with rx, ry, rz in the instance panel of my Geo but I don't understand why ...

Re: Adding two noise CHOPs together

I tried that but unless I am missing something, when I do that, it adds everything and I get one value in the output.
I have two noise chops and when I use the combine chop from the math chop it adds everything to one value.

Re: Adding two noise CHOPs together

What you're looking for is the Combine CHOPs parameter on the Math CHOP, specifically the "Add" option.

Python + onCook Question

I want to use noise to randomly fire a Pulse event. There's probably a bunch of ways to do this, so I'd be open to all options. The way I'm trying to do it is to create a Noise Chop -> Logic Chop (to convert to 0/1) -> Script Chop. Inside the Script Chop I have the following ...

Re: ParticlesGPU

... GPU as forces. One idea to try possible is to add a time-slice mode noise CHOP that has run through a math CHOP and had its values re-ranged and apply this to the radius ...

Re: Using audio to drive noise

plugging your audio into an analyze CHOP, commonly set to RMS, and exporting that value to a parameter in the noise SOP exactly. i've achieved a similar effect like this: Beat or Analyze CHOP -> math (to control ...

Re: Varying lag velocity/acceleration

... example... In it, I'm using the numSamples to index into the wave chop for a maximum slope. I then use it to lag the noise CHOP. it does what i'd expect if lag per sample is turned OFF... but when I turn it on, ...

Re: Using audio to drive noise

One way you might think about is plugging your audio into an analyze CHOP, commonly set to RMS, and exporting that value to a parameter in the noise SOP. Matthew Ragan has a lot of great tutorials on working with audio in TD.
