Simple Strand HDA is a procedural asset developed in Houdini to streamline the creation of custom DNA strand models.This project addresses the need for a fast, intuitive solution in the medical animation and VFX industries. Instead of manually modeling complex helical structures, artists can use this HDA to generate production-ready DNA geometry in seconds, maintaining complete artistic control over every element.

Technical Specifications & Control Features:

Global Controls: Dynamic adjustments for strand length, twist frequency, and segment count.
Backbone Settings: Independent control over mesh thickness, resolution, and color attributes.Base Pairs: Detailed parameters for thickness, geometry carving, color maps, and color offset variations.
Pipeline Utilities: Integrated built-in animation controls, automatic Upres geometry switching, and a center-pivot correction system.
