+# Godot Rendering — Quick Reference
+
+Last verified: 2026-02-12 | Engine: Godot 4.6
+
+## What Changed Since ~4.3 (LLM Cutoff)
+
+### 4.6 Changes
+- **D3D12 is the default rendering backend on Windows** (was Vulkan)
+- **Glow processes before tonemapping** (was after) — uses screen blending mode
+- **AgX tonemapper**: new white point and contrast controls
+- **SSR overhauled**: better realism, visual stability, and performance
+
+### 4.5 Changes
+- **Shader Baker**: Pre-compiles shaders to reduce startup time
+- **SMAA 1x**: New anti-aliasing option (sharper than FXAA, cheaper than TAA)
+- **Stencil buffer support**: Enables selective geometry masking/portal effects
+- **Bent normal maps**: Directional occlusion encoded in normal map textures
+- **Specular occlusion**: Ambient occlusion now correctly affects reflections
+
+### 4.4 Changes
+- **`RenderingDevice.draw_list_begin`**: Many parameters removed; optional `breadcrumb` added
+- **Shader texture types**: Changed from `Texture2D` to `Texture` base type
+- **Particles `.restart()`**: Added optional `keep_seed` parameter
+
+### 4.3 Changes (in training data)
+- **Compositor node**: `Compositor` + `CompositorEffect` for post-processing chains
+
+## Current API Patterns
+
+### Post-Processing (4.3+)
+```gdscript
+# Use Compositor node — NOT manual viewport shader chains
+# Add Compositor as child of WorldEnvironment or Camera3D
+# Create CompositorEffect resources for each post-process step
+```
+
+### Anti-Aliasing Options (4.6)
+```
+Project Settings → Rendering → Anti Aliasing:
+- MSAA 2D/3D: Hardware MSAA (quality but expensive)
+- Screen Space AA: FXAA (fast, blurry) or SMAA (sharp, moderate cost)  # SMAA new in 4.5
+- TAA: Temporal (best quality, ghosting on fast motion)
+```
+
+### Rendering Backend Selection (4.6)
+```
+Project Settings → Rendering → Renderer:
+- Forward+ (default): Full featured, desktop-focused
+- Mobile: Optimized for mobile/low-end, limited features
+- Compatibility: OpenGL 3.3 / WebGL 2, broadest hardware support
+
+Windows default backend: D3D12 (was Vulkan pre-4.6)
+```
+
+## Common Mistakes
+- Assuming Vulkan is the default backend on Windows (D3D12 since 4.6)
+- Using manual viewport chains instead of Compositor for post-processing
+- Using `Texture2D` in shader uniform types (use `Texture` since 4.4)
+- Not using Shader Baker for projects with many shader variants
