They precompute the effect of objects that emit light and the effect of static geometry to simulate the behavior of complex light in real-time. [VoxelGI]s need to be baked before having a visible effect. However, once baked, dynamic objects will receive light from them. Furthermore, lights can be fully dynamic or baked. [b]Procedural generation:[/b] [VoxelGI] can be baked in an exported project, which makes it suitable for procedurally generated or user-built levels as long as all the geometry is generated in advance. For games where geometry is generated at any time during gameplay, SDFGI is more suitable (see [member Environment.sdfgi_enabled]). [b]Performance:[/b] [VoxelGI] is relatively demanding on the GPU and is not suited to low-end hardware such as integrated graphics (consider [LightmapGI] instead). To improve performance, adjust [member ProjectSettings.rendering/global_illumination/voxel_gi/quality] and enable [member ProjectSettings.rendering/global_illumination/gi/use_half_resolution] in the Project Settings. To provide a fallback for low-end hardware, consider adding an option to disable [VoxelGI] in your project's options menus. A [VoxelGI] node can be disabled by hiding it. - [b]Note:[/b] Meshes should have sufficiently thick walls to avoid light leaks (avoid one-sided walls). For interior levels, enclose your level geometry in a sufficiently large box and bridge the loops to close the mesh. To further prevent light leaks, you can also strategically place temporary [MeshInstance3D] nodes with their [member GeometryInstance3D.gi_mode] set to [constant GeometryInstance3D.GI_MODE_BAKED]. These temporary nodes can then be hidden after baking the [VoxelGI] node. + [b]Note:[/b] Meshes should have sufficiently thick walls to avoid light leaks (avoid one-sided walls).
