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. [b]Note:[/b] Only usable when using the Vulkan backend (Clustered or Mobile), not OpenGL. </description> <tutorials> </tutorials> </class>
