Baked shadows are pre-calculated and stored in a texture, while real-time shadows are calculated in real-time based on the position and movement of objects.

To enable baked shadows, you need to enable the “Baked Shadows” property in the light source node. This will generate a shadow texture that can be applied to objects in your scene. Baked shadows are ideal for static objects that do not move or change shape during gameplay.

On the other hand, real-time shadows are more suitable for dynamic objects that move or change shape. To enable real-time shadows, you need to enable the “Shadow” property in the light source node. This will cast dynamic shadows based on the position and movement of objects in your scene. Real-time shadows can greatly enhance the realism of your game but may require more computational resources.

In addition to light sources and shadows, Godot also provides various techniques to enhance the visual quality of dynamic lighting. One such technique is ambient occlusion, which simulates the softening of shadows in areas where objects are close together. This can be achieved by enabling the “Ambient Occlusion” property in the light source node.

Another technique is light attenuation, which simulates the decrease in light intensity as it travels further away from the light source. This can be controlled by adjusting the “Attenuation” property in the light source node. By tweaking these properties, you can achieve the desired lighting effects in your game.

In conclusion, understanding the basics of dynamic lighting and shadows in Godot is essential for game developers looking to create visually stunning games. By adding dynamic lighting and shadows, you can greatly enhance the visual appeal and realism of your game.
