Could someone make a tutorial on how to make, save and upload skins for mods? already many thanks

There is a small skin guide on LFS Manual - Creating a skin texture.

If you assign a skin to some of the default colours of your mod, it will automatically be included with the mod when you upload it.

thanks, its too hard than common skins

I made these videos showing how do I create skins... It can be used in Mods too...
