I NEVER SAID I WAS A SKINNER GOD. i have made other stuff other than the pink spit and the c47 but there works in progress i only spend maybe 10 minutes a day with skinning. and i do know the steps gone through with skinning. and it is all in the help file.
guess what im not the only person to send people t othe help file.
To change the skin on a plane or object, first select a shape from the Available Shapes list, then click the Save Texture button and close the Terrain Editor. All of the textures for that shape will be exported as .bmp files into your ../HTC/ahedit/terrains/myterr/savedtex folder. Before editing any of the .bmp files, be sure to make a copy of the file first.
that handy little thing came strait from the help file. after that you just edit the .bmp
not that difficult. anyway until we get a skinning forum ask your skinning questions in the TE forum.
