## What it is
Ray-MMD is a free shader library and extension pack for MikuMikuDance that adds physically-based rendering (PBR) via HLSL shaders on the MikuMikuEffect (MME) plugin. It provides high-quality lighting, materials, and post-processing effects for MMD animations.

## Use cases
- add physically-based rendering to mikumikudance animations
- render mmd models with realistic lighting and materials
- apply post-processing effects like bloom and anti-aliasing to mmd videos
- create high-quality mmd renders with pbr shaders
- enhance mmd scenes with skybox and environmental lighting

## When to choose
- you use MikuMikuDance and want realistic PBR rendering
- you want a free, community-standard shader pack for MMD
- you need advanced lighting, materials, and post-effects in MMD

## When to avoid
- you don't use MikuMikuDance or MikuMikuEffect
- you need a general-purpose 3D renderer outside MMD
- you need a cross-platform solution (it targets DX9/Windows)

## Facets
