 ### Step 5: Render/Bake
 
 When baking we have the option to either bake in all the lighting, both indirect and direct, or just the indirect lighting, also known as global illumination or bounced lighting, and use realtime lights in Ignition for the direct lighting and shadows. With the latter method we get sharper lighting and shadow detail as well as more accurate lighting on our dynamic objects however performance will be impacted by having more real time lights. Even with all the lighting baked it’s still a good idea to have one realtime light such as a large point light or directional light works particularly well in order to enhance the effects of the physically based materials.
