Open Source HVA Builder 2.1

Open Source HVA Builder is a lightweight, open-source utility for creating and editing HVA (Hierarchical Voxel Animation) files used with Westwood-style voxel models, most commonly in Command & Conquer: Tiberian Sun and Red Alert 2 modding. It lets creators define per-frame transformations for individual voxel sections—such as turrets, barrels, tracks, or deployable parts—so in-game models can rotate or move as intended.

Key features:

• Opens and saves .HVA files and loads the associated .VXL model for context
• Per-section, per-frame editing of rotations and translations
• Timeline tools to add, duplicate, and reorder frames
• Visual preview to verify alignment and motion
• Utilities for alignment, frame copying, and batch adjustments

Open Source HVA Builder is aimed at modders and artists who need precise control over voxel animations, such as turret recoil or deployment sequences. It is typically used on Windows and may run on other platforms via compatibility layers like Wine. Developer: unknown.
