Example for Deformation Wrangle SOP VEX?

[catchyid]

Hello,

I am doing a mesh deformation and found this SOP node "Deformation Wrangle" which runs VEX code, does anyone has an example on how to use it? I use lots of vex  wranglers, but never seen this one before?

Thanks,

the dropdown list gives you the Twist ?

Thanks, I see a sample code. What made me initially curious is: If this node runs vex code on points to deform them, then why cannot just use a normal point wrangler? Also, I need to check the derivatives option because I am not sure how to use it. Okay, I admit, I need to read and test more

because it computes the derivatives and the full per point transform from them (or explicitly using xform) to transform the transformable attributes

if not providing xform your function however needs to be continuous based on pos variable for derivatives to be properly computed
