NodeCraft
The Custom Textures feature is for mapmakers and server admins who want to add custom textures to Pokémon or Statues via resource packs in a similar way that Pixelmon adds Special textures.
To use this feature you will need to be capable of editing nbt data using an nbt editor, or a sidemod, or using the command entitydata.
Custom textures are loaded from assets/pixelmon/textures/pokemon/custom-%value%/ Where %value% is a string value loaded from the nbt tag "CustomTexture" of a Pokémon or a Statue.
The "CustomTexture" nbt tag's value must be lowercase, but can otherwise be anything you like. For example, if you have a Ivysaur with the CustomTexture nbt tag value of "shadow" then the full texture path will be assets/pixelmon/textures/pokemon/custom-shadow/ivysaur.png. Or if you have a shiny Tyranitar with the CustomTexture tag value of "ghost" then the full path of the texture would be assets/pixelmon/textures/pokemon/custom-ghost/shinytyranitar.png.
For example /entitydata @e[type=pixelmon:pixelmon,name=Ivysaur] {CustomTexture:"shadow"}. This command will change every Ivysaur out of its Poké Ball to the custom texture "shadow", placed in the example above.
Special note to server owners
This feature was added in Pixelmon Reforged 6.2.0 without a fallback implementation. Any players without your custom resource pack loaded will see the black and purple error texture instead of the default textures. This is planned to be fixed for a future version.
If you have people capable of making or editing textures, please consider volunteering their time or skills to help the Pixelmon mod. The less the core team has to do the more they can work on development of the mod.
