RTT & Effects System

Render-to-Texture (RTT) is used for complex scene composition and group-level effects.

The RTT Pipeline

1. Isolation: Layers within a group are assigned to a specific RenderLayer.
2. Dedicated Camera: A secondary camera renders only that RenderLayer into a Texture.
3. Projection: The resulting texture is then drawn back into the main scene.

Unified Effect Shader

For individual layers, we use the UnifiedEffectMaterial. This shader is designed to apply multiple effects in a single pass to maximize performance:

• Masking
• Wipe
• Stretch Segment

By combining these, we avoid multiple render passes and minimize GPU state changes.
