Included corresponding compressor in "utils/exporters/utf8" (prebuilt exe for Windows plus slightly modified C++ source code). Use UTF8 format with caution, it is very neat but has quite a few limitations: - number of vertices < 65536 (this is after optimizations in compressor, input OBJ may have even less) - models must have normals and texture coordinates - texture coordinates must be only from <0,1> - no materials support yet - models are scaled and offset (copy numbers from compressor and use them as parameters in UTF8Loader.load() )
