Description
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 RenderingDevice backend (Forward+ or Mobile renderers), not Compatibility.
