The Solaris (Procedural Fire, Smoke, Energy and Trails Shader + VFX) v1.1.1 asset enables the creation of fully procedural, animated fire, smoke, and energy-like effects using a single versatile shader. It supports both static meshes and Unity's particle system and trail renderer components. Real-time transparent lighting is fully supported, and no textures or custom geometry are required—everything is procedurally generated, including tessellation, allowing the use of simple primitives like quads, spheres, and cylinders.
The package includes example prefabs and a demo scene showcasing a wide range of effects: fire (such as in a fireplace or campfire), colored smoke, volumetric fog with real-time lighting, glowing ember particles, 2D and 3D energy shields with multiple layers, wispy magical trails, depth-based transparent outlines, overlay/intersection effects, velocity and position transfer (mesh bending based on movement), warpdrive/hyperspace tunnels, volumetric animated light shafts, and volumetric shadows.
Laser beams can be created using Unity's lines, trails, or meshes, moving through volumetric fog or smoke. Additional interactive features include interactive fire and torches, bendy, rotation-aware flamethrowers, and particle fire trails with lit fog or smoke.
The shader is highly parameterized with over 100 exposed values, allowing for infinite customization and performance tuning across different GPU capabilities. It requires a minimum shader model of 4.5. A second, lightweight shader is included for rendering dense fog or smoke, using a base texture and normal map to reduce computational load while maintaining procedural randomness and avoiding repetition. This lightweight option helps manage performance issues, especially on lower-end hardware or in scenarios with high overdraw.
