UV-Packer for Unreal Engine


The main advantage of UV-Packer is the automatic workflow of rescaling UV clusters relative to the surface they cover on the mesh and arranges them to utilize as much space on the UV map as possible. This increases the texture quality for the mesh, fixes overlapping UV and results in optimized light maps.
