Hi! I´m new here, and I´m also new to Houdini. Coming from a bunch of other applications I know the workflows from there. But things are not what I´m used to in Houdini. I´ve been modelling an object in Silo containing several parts and exported it to obj. In Houdini the model is in the one and same obj node. How do I split it into seperate parts without selecting the polygons and Modify/Extract in the shelf?
