Custom Textures

To add custom textures, place PNG files in:

Example for a custom player skin:

npc/minecraft/player/texture.png

The texture will appear in the editor’s dropdown.
You can do this for all entities, even those from other mods.

npc/modid/entity/texture.png

Your file name will appear in the dropdown menu, so choose it carefully.
