i’ve played around with shaders in houdini and pick up an old idea, which one of my last productions. a displacement shader for fracture pieces.
this shader allows me to use pre-fracture geo and add extra displacement only in inside structure without adding high polycount to my geo. this works really good for concrete surfaces.
this version of the shader displace also the edge on the cracks. this works good on dynamic fracturing. for pre-factured, i used a “forEach” node to acitvate the displacement on impact time, otherwise you will see the cracks before the impact.
