High-Performance Geometric Dissolve Effects
When you need more than a simple alpha cutout, Advanced Dissolve Unity 2021.1.0 provides a mathematically sound way to handle object transitions using geometric volumes. This asset is particularly useful for developers who need to integrate dissolution effects into existing Shader Graph workflows without manually calculating local-to-world space geometric intersections for every vertex.
Integration Tips
- Shader Graph Integration: Rather than using the standalone shaders, use the provided Subgraphs within your own Shader Graph files. This allows you to combine the dissolve effect with your existing PBR or stylized textures while maintaining full control over the edge noise and emission.
- Global Illumination Impact: Since the emission from the dissolve edge can be visible to Unity’s GI system, ensure your edge width isn’t so thin that it causes flickering in the lightmap or probe updates. Adjust the ‘Solid’ vs ‘Smooth’ edge setting based on your project’s light bake resolution.
- Geometric Controller: Use the provided C# scripts to move the geometric masks (Spheres, Cubes) at runtime. For performance, batch your dissolve calls if you have multiple objects dissolving simultaneously to minimize property updates to the material.
Best Use Cases
- Sci-Fi Environment Transitions: Perfect for ‘cloaking’ effects or futuristic doorway transitions where the environment needs to peel away based on a player’s proximity or a specific world-space coordinate.
- Character Death/Spawn Effects: A more performant and visually interesting alternative to simple fading, especially for mobile games where transparency and overdraw can significantly impact the frame rate.
