In the Clip SOP, would it be possible to specify the origin point? Currently, it just assumes 0,0,0. a transform matrix input would also be super handy to specify the direction and origin. You could use the object chop to query some object in the scene and then just plug that in.
I would also love this node in POPs, currently I have to convert to sops and back to POPs. This node is seriously underated use it all the time.
