The built-in GPU-based lightmapper for use with LightmapGI.
LightmapperRD ("RD" stands for RenderingDevice) is the built-in GPU-based lightmapper for use with LightmapGI. On most dedicated GPUs, it can bake lightmaps much faster than most CPU-based lightmappers. LightmapperRD uses compute shaders to bake lightmaps, so it does not require CUDA or OpenCL libraries to be installed to be usable.
Note: Only usable when using the Vulkan backend (Forward+ or Mobile), not OpenGL.
