Procedural Greebles HDA for Houdini

How to use the Procedural Greebles HDA in Houdini to add extra geometry detail / greebles to almost any object — a free usage walkthrough. What's covered: • Running the HDA over built-in or custom geometry and groups • Controlling extrusion / inset depth, random positioning, scale, bevel and orientation • Iteration count and the colour / luminance mask • The output parameters and groups the asset exposes • Using the included sample scene and ready-made Redshift shader Compatibility: built for Houdini FX/Indie 17–18 and tested with Redshift 3.0.27 — the node setup works with any renderer. Tip: feed it geometry made of quads or triangles for the cleanest result. Get the Greebles HDA, the sample scene and the Redshift shader from the project-files card above.
