Luma Based Ambient Occlusion 2
Luma Based Ambient Occlusion is a full-screen effect that fakes depth shading from color alone, giving flat 2D scenes real relief, on Built-in and URP.
Key Features
Simulates occlusion from color information alone, no depth buffer required -- perfect for flat 2D scenes
Adds depth shading and relief feeling to otherwise flat 2D images -- instant visual richness
Works with both orthographic and perspective cameras -- fits any 2D or 3D setup
Depth-independent, compatible with 2D, transparent objects and particles -- no exclusions
Color bleeding support -- richer, more natural occlusion tones across your scene
Directional occlusion control -- shape the AO direction to match your art
Combine with depth-based HBAO or Beautify in 3D scenes -- experiment for best results
Supports Built-in and URP including Render Graph, Unity 2023.3 and Unity 6 -- demo scene included
