Features:
Volumetric Aurora Rendering: High-performance rendering powered by Raymarching techniques.
Dynamic Shape Generation: Supports multiple methods for determining aurora forms through 2D texture sampling:
- Simplex Noise Dual Sampling: For creating scattered, curtain-style aurora patterns.
- Spline-based DF Textures: For defining precise, custom paths for the aurora.
- Potential Flow Simulation: Provides basic directional movement using a simplified flow model.
In-Engine Baking Tools: Built-in utilities to bake custom DF (Signed Distance Field) and Potential Flow textures directly within the editor.
Comprehensive Preset System: Includes pre-configured presets specifically optimized for the three core generation types
(Simplex Noise, Spline DF, and Potential Flow), with full support for:
- Creating, modifying, and managing custom user presets.
- Robust Save/Load functionality to preserve and reuse your aurora configurations.
