The first version of “Houdini Easy Compile Block” is now available. It allows you to compile a sop forloop or a selection of nodes pretty easily, it will create the compile sop ( end and begin ) as well as update the expression and create spare inputs for you if needed.
For more info about compile sop, look at sidefx masterclass: https://vimeo.com/222881605
Available for free (still in beta), here.
