Hi. Another beginner question!

I was wondering - what are the best approaches to create object level expressions to modify object transformations etc. For example I would like to make object automatically orient to the direction of its movement ( just an example ). I know i can write hscript/python directly in objects rotation parameters, but that is not very convenient ( I have to copy expression to each field ).
What I would like is like a SOP level Python node or VEXpression field in object level - so I could do some calculations and update all needed object properties from there.

What are recommended workflows for such things?

you can make Python based object level HDA

File/New Operator Type
choose Python Type/Object Operator

or process your transform on points in SOPs, then reference in transform parms of your object
or use CHOPs

:idea: that is exactly what I want! I did not know about creating new operator types! Awesome!!
