I think here is problem:Rename original cmd file: Kabina-Su-27-1.cmd
And here is skins file:
models
{
lod = {"Kabina-Su-27-1", 800000}; (this is orig. file cmd in shape folder)
lod = {"Kabina-Su-27", 800000}; (this is new lom file in shape)
skin
{
value = 1.0;
material = {"Master instruments", "Standart", "Master instruments.bmp"};
material = {"Engine fuel panel master", "Standart", "Engine fuel panel master.bmp"};
material = {"Panels", "Standart", "Panels.bmp"};
material = {"MFCD", "Standart", "mfcd panel.bmp"};
material = {"panels 2", "Standart", "panels 2.bmp"};
}
