This is how to replace 1K skin texture with 2K.   (1) Read TMC file's TTGL. They mean:  - texture count: 13  - texture total size: 5876352  - texture offsets: 16, 10304, ..., 4473424 (13 values)  - texture sizes: 10288, 10288, ..., 1402928 (13 values)   (2) Read TMC file's LHeader. They mean:  - offsets: 128, 5876480, 7027072 (for texture/vertex/face data block in TMCL)  - sizes: 5876352, 1150512, 122992 In TMCL file, you can find the first
