Drag & drop doesn't work on a chop

Hello,

I’d like to create references from a topto CHOP but I can’t make a drag & drop from the CHOP… why ?

Hi @snaut ,

I’d like to connect the red channel to the z-rotation of cam1 comp :

On this capture screen, I wrote directly op(‘math4’)[‘r’] in the z-rotation.

Normally is it possible to make a drag and drop and to avoid writing code ?
Maybe I’ve missed something… :thinking:

Hi @vj_dobermann,

when dragging and dropping from a multisample CHOP, you need to activate the viewer and grab the name of the channel and drag it onto the parameter.
Just as a note, the result might be not what you expect as the value being used in the parameter will be the value of the CHOP channel at the current frametime. Usually you would want to use single sample CHOP channels to drive parameters.
