To bake a Unity Assets 3D model, prepare the model with non-overlapping UVs and materials, then use Unity’s Lighting window (or tools like Substance Painter) to precompute static textures (e.g., AO, lightmaps) or lighting data.
- **Why bake?** It converts dynamic elements (like real-time lighting) into static maps—speeding up rendering for static models/environments while preserving quality and saving GPU resources. - **Beginner tip:** Start with Unity’s Lightmapping tutorial using a simple model. Critical: Avoid overlapping UVs to prevent texture artifacts.
Baking optimizes static content; focus on clean UVs and basic tests first to get started smoothly.
