The difference is especially noticeable with emissive materials or areas that get little to no direct lighting. Each bake quality mode can be further adjusted in the Project Settings. +- **Supersampling:** This creates the lightmap at a higher resolution and then + downsamples it. This reduces noise and light leaking, and produces better + shadows with small scale details. However, using it will increase bake times and + memory usage during lightmap baking. The **Supersampling Factor** changes the size + the lightmap is rendered at before downsampling. - **Bounces:** The number of bounces to use for indirect lighting. The default value (``3``) is a good compromise between bake times and quality. Higher values will make light bounce around more times before it stops, which makes
