1.Unzip tU-144TEXT 2.Copy the content of TEXTURE.BASE to THE rest texture folders named TEXTURE This is because I've only modified the five .bmp files wing_t, tail_t, fuse01_t, fuse02_t, fuse03_t, so every folder has to be completed with the rest of the texture files 3.Copy the folder TU144TEXT into your fs9/aircraft/Tu-144 subfolder. In order to do more easy the installation, I've included the classic Tu-144/Tu-144D/tu-144LL (by Thomas Ruth and Claudio Mussner) renamed folders/files needed: models, panel and sounds and .air 's NOTE: You'll obviously need to be installed the other Tu-144 claSsic folders: Effects into your fs9/effects subfolder sounds into your fs9/sound subfolder Gauges into your fs9/gauges subfolder
