How to access an attribute inside CHOPs for parameters?

[magneto]

Hi,

I want to vary a parameter using a SOP attribute. For example I have a Lag CHOP and I want to vary the Lag parameter using the SOP attribute for each point. How can I access the SOP attribute inside a CHOP parameter?

 

Thanks

Geometry CHOP and use the animated method.

Thanks Edward, I used the $C inside a point expression. Because I have a lag point attribute and I want to load this value into Lag parameter for each point. Geometry CHOP will bring the attribute into CHOPs but not alter the parameter on a CHOP node unless I am missing something.

Basically I want to vary CHOP node parameters for each point separately.

That then depends on whether the parameter in question is evaluated per channel or not. This varies drastically depending on the particular node. In the Lag CHOP case, that's true. So then you can just use a point() expression even.

Thanks Edward, is there a way to know if a node is evaluated per channel or not for CHOPs? Using point expression with $C like you said worked. I just didn't know what $PT would be that's why I was confused.

Also happy new years

I think most CHOP parameters do but unfortunately you really can't tell until you try.
