Rock Generator: HDA

HDA

As a way of practicing Houdini, I have been learning how to make my scripts more efficient with the use of Houdini Digital Assets or commonly referred to as HDAs. Over the past couple of months, I have learned Houdini through online resources and my own exercises. Rock Gen is a public HDA I posted on Gumroad as a starter on how to setup these HDAs to make my scripting more efficient and how to share them with others as well.

Rock Gen is an locked .hda that makes rock shapes and add noise to the primitive.

GEOMETRY

Geometry is the built-in given type, based on river rocks.

Seed gives variation

CLIPPING

Clipping cuts the geometry in two different ways that are common in rock types.

CRACKING

Still WIP, but for now, it gives two different types of cracking attributes to the geometry.

NOISE

Noise adds the final touches to the roughness, smoothness, or edges of the geometry.

Future Improvements:

• Adding more variation to the noise.

• Ability to use custom geometry

• Scatter option onto geometry

Tools:

Houdini 19.5
