Our Destructible Road Signs have released and are now available on the marketplace! Here you can find the documentation on the Destructible Matrix Editor. Using that documentation, you can set up the destructible to behave exactly how you want (I have set up default settings already and you can tweak those). According to EPIC’s Tim Hobson one of the variables in the destructible editor’s matrix, ImpactResistance, does not work in version 4.7 and is resolved with the 4.8 version.
