Add transparency support for LightmapGI Currently when baking lightmaps users have to choose between transparent objects casting shadows as if they were fully opaque, or not casting shadows at all. This has been a major limitation in both the quality of lightmap baking and the ergonomics of the lightmap baking workflow.

supports advanced global illumination techniques such as lightmapping (including SH lightmapping), Voxel GI (which is fully real-time) and SDFGI (which is a single click, open world GI solution). The most common types of streaming are: Texture streaming : All textures are loaded in a tiny size by default.

Introducing the new "last minute" lightmapper

Mircosoft Game Dev

DECEMBER 13, 2017

The solution to these problems is to add support for a more traditional lightmapper (pre-baked light texture). Light is precomputed offline and rendered to a texture, which is then used by the geometry. Lightmapping is a very cheap operation, so it should run fine even on low end mobile. What are the performance limitations?

Fixed an issue where Mesh objects created through MeshUtils.createMesh caused data anomalies. Fixed an issue where the setter for the Mesh:: _ hash attribute was not bound. When the user turns on high-precision lightmap baking, 16-bit colors are used instead of 8-bit colors, and AO channels are baked separately.

Notably, Windows users could experience crashes when baking lightmaps. Import: Print a warning when importing a repeating NPOT texture in a GLES2 project ( GH-48817 ). Import: glTF: Improved error handling around invalid images and invalid meshes ( GH-48904 , GH-48912 ). was thus subject to this crash when baking lightmaps.

Godot 4.0 gets SDF based real-time global illumination

SDFGI is something akin to a dynamic real-time lightmap (but it does not requiere unwrapping, nor does it use textures). Ensure your meshes are marked as "Static Bake", then enable SDFGI in the Environment settings. What can it do? As long as walls are thicker than a voxel for a given cascade, light won't go through.

x CPU lightmapper and adding a new debug draw mode for visualizing the texel density of lightmaps. Previously every LightmapGI node used to store its lightmap atlas in a single large image. I modified the implementation to allow saving the lightmap atlas as multiple images if it doesn't fit inside a single image.

No lightmaps or anything of the sort are required, providing a very quick and efficient workflow. For low-end systems or mobile devices, we provide a more classical lightmapping workflow. Godot will pick the right compression for textures when importing for mobile, and supply them over the network. It's also very easy to use.

Use baked lightmaps instead. Godot now supports 2D meshes , which can be used from code or converted from sprites to avoid drawing large transparent areas. CSG tools have been added for fast level prototyping, allowing generic primitives and custom meshes to be combined via boolean operations to generate more complex shapes.

Last but not least, lightmaps baking is now done using the GPU to speed up the process significantly. Several new optimization techniques are also at your disposal, such as occlusion culling , automatic mesh LOD , and manual HLOD using visibility ranges , made possible by Joan Fons ( JFonS ), and Juan. has been added by Je06jm.

Heyyy, this pretty much looks like the sky projected onto the meshes, that's better! At that point of development, the sky reflection didn't respond to the camera position, so it basically looked like the sky was painted ontop of the mesh.
